    Hi there,
    I´m looking for a good statisticsoftware. A lot of persons told me to buy MINITAB, a some other told me about STATGRAPHICS.
    Is Statgraphics good and useful for Six Sigma?
    Would you prefere MINITAB?
    Thanks,
    Ralf

    Ralf,
    The basic stats programs aren’t really much different. Formulas are formulas. They haven’t changed much in several years. So selecting software should really be decided on other issues.
    Remember who your users are. Are they people with a statistics background or not. The basic Voice of the Customer issues. Remember if you have customers that are driving you to SS you had better look at staying compatible with them. If you are going to spend time trying to resolve how the software is doing analysis that will be nonvalue add time.
    I haven’t used Statgraphics since 91 so I do not have a good reference point. I am partial to Minitab just because of the great support for the SS initiatives.
    Good Luck.

    I use minitab for my analyses, but I guess I would say choose the one that most fits your use. If it’s six sigma, then look at who’s advertising on this site…minitab, not statgraphics. Does that mean that statgraphics doesn’t support six sigma as much as minitab — probably. Can anyone else verify?

    Statgraphics can do most of what Minitab, JMP, and Statistica can do, but with a slightly difference environment. All four have most of the tools used by BBs, though Statistica tends to be much more expensive if you buy the modules needed to equal the capability of the others.
    Strongly suggest you download their demos and drive each for a little while – its the only way to know which one feels right for you and yours (I agree with Mike’s customer advice if applicable to your company).
    My order of preference these days: Minitab, StatGraphics, JMP, Statistica (mostly due to cost – might be second otherwise).

    This got me thinking that it isn’t so much what the software WILL DO as what it won’t do. It also got me thinking about the way the different companies are copying one another’s ideas. Kind of interesting:
    Statgraphics created “StatFolios” that saved all results in a single file – Soon Minitab had similar “project” files – JMP doesn’t have this capability…yet.
    Statgraphics created the “StatAdvisor” to give assistance with interpreting the output – Minitab added the “StatGuide” to to a similar thing – JMP doesn’t have this capability…yet.
    Minitab had macro capabability – JMP added macro capability – Statgraphics doesn’t have this capability…yet.
    JMP had the “Journal” which allows the user to transfer selected output items to a rich text file report format – Minitab created “ReportPad” – Statgraphics created “StatReporter”. I don’t know which came first.
    JMP has very interactive graphics – Minitab has some interactive graphics, but it is limited (brushing, an interactive optimizer in DOE, graph editing) – Statgraphics 5 says it has interactive graphics, but sounds much like Minitab’s.
    Statgraphics has the ability to put multiple graphs/output on a single page – Minitab can do this too – JMP doesn’t really try to do this.
    Minitab started creating “one-page reports” for summary statistics, GR&R, process capability, etc… – Statgraphics clearly is trying to do the same, but in version 5 they don’t look as good as Minitab’s yet. JMP hasn’t really tried to do this type of reporting (JMP doesn’t really seem to care about outputting its results too much).
    Minitab does reliability analysis – StatGraphics then added RA – JMP does a little RA.
    Minitab does gage linearity – StatGraphics then added GL. – JMP doesn’t do GL.
    Nobody uses as much magenta, cyan, and lime green as Statgraphics though – ugh!!
    List Prices:
    Minitab: $1195
    StatGraphics: $1649 (with same tools as Minitab – SG now has modules)
    JMP: $895
    I don’t have too much familiarity with Statistica, so I won’t comment on that package. I looked at it about 3-4 years ago and found it hard to figure out intuitively – and I’ve spent 15 years using stat software. It might be better now.

    JMP can interpret your plots, using one of the options on “preferences” on the start page. Just check the box marked “show explanations” on the “general” tab.
    Used to use a package for DOS called RS1 which had a really good explanation parser. Unfortunately the Windows version does not have the same functionality and has much less breadth of applications. It was also much more expensive than any of the modern software.

    Hallo Ralf,
    Our company with thousands of employees has selected MINITAB. I have not used any other tool so far, but such a decision for such a big company must be supported by serious investigations, I believe.
    Otherwise, MINITAB does really everything for me what I need as BB. There are surely some “bugs” to improve, but where are not ?
    Buying MINITAB, you won’t do anything wrong.
    Vladimir.

    In my role – Senior Staff Statistician – I would recommend Statistica. I have been using Statistica for about 8 years now.  It is the most powerful statistical software. We also have it on our network so all of our engineering and technical people have access to it. Statistica can be quite expensive (>$3000) if all the supplemental modules are added so I would suggest right sizing for your application. I use all the modules in my work but you probably will not.  There are two modules you will need to cover the applications addressed in this forum: Statistica Basic plus the Industrial Sysyem add-on.  The add on gives you Quality Control Charts, Process Analysis, and Design and Analysis of Experiments.  You may also want to take a look at the on-line Statistical manual that can be found at http://www.statsoft.com and ask for a demo disc before making your purchase.  Statsoft also provides in-house training if needed but the interactive portion of the software leads you through many of the procedures.

    These threads contain some excellent discussion! A couple more comments:
    Statgraphic’s Statadvisor feature is EXTREMELY useful for training purposes for folks who are new to stats. Rather than lots of clicks, etc., it’s always there if turned on, and it both explains and guides many evaluations. It can save BBs and MBBs lots of time in training others.
    A package I haven’t seen mentioned should be considered as well. Design Expert from Stat-Ease is, by far, the most advanced, yet user friendly DOE software ever, and is supported by experts at StatEase, the software’s home company. Their comprehensive courses on factorials, mixtures, response surfaces, and robustness are excellent investments for any company anticipating DOE as part of their continual improvement efforts. (This is an unpaid commercial for a truly outstanding firm and product.)

    In my oppinion, Stata (College Station, TX http://www.stata.com) is the best general purpose statistical software package out there. Is easy to learn, fast and has more statistical features than any other, with the exeption of perhaps SAS. However SAS is expensive and it has a long and steep learning curve. This is not true with Stata. It is great for beginners and advance users. It is a great product and technical support is the best of any software company.

    This is not true. Statistical software has change a lot. There are many more ways of estimating parameters and standard errors available now than before. In addition, with faster computers and  more memory, procedures not available in the past such as MCMC or even permutation tests are now becoming more available. Also there is variability in how estimation commands are programmed and likelihood functions maximized. These differences can result in different results reported by different software providers. If you are serious about your statistics, then stay with the “big boys” such as STATA, SAS or S-PLUS, and stay away from software companies that produce statistical software as a by-product of other work (such as Excell). “Do one thing and do it well” is important in the statistical software business.

    I would never never NEVER recommend SAS or S-Plus for a typical Black Belt or Green Belt.
    They are far more complicated than necessary and tend not to have the “prepackaged” toolsets useful for methods such as GR&R and process capability. Yes they can do just about anything, but it can be serious work to get the same output as provided by Minitab, Statgraphics, JMP, etc. . . ..

    I went to http://www.stata.com/info/capabilities/ to see Stata’s capabilities. As a general purpose statisical package the list is impressive, BUT what concerns me, with respect to use by Black Belts & Green Belts is the absense of any mention of design of experiments, measurement system analysis, gage R&R, gage linearity, process capability, statistical process control (SPC), pareto charts,  . . .
    It appears to be very nice software, but its just not made for the Six Sigma (or industrial statistics) audience.

    Mario,
    Let’s keep track of who wrote what. You are referencing me not Ralf. Now that that difficult piece of analysis is through lets get to your enlightened response.
    The big boys are the boys that understand the customer and the requirements of the job. We have done a lot of deployments and the requirements of the software – particularly Minitab has changed to meet the requirements of how the job was being done and the tool which were predominately used. If you are enamoured with some obscure capability that some other program gets used by the Big boys then you are not representative of the BB population and do not understand a concept as Pareto.
    As far as formulas changing – basic stats, t tests, ANOVA, etc has not changed. The point is software as software goes is not the issue. Excel can be taught to do most of this. The issue is using the appropriate software for the task and that means understanding the people who will use it.
    You might want to be a little introspective on this and understand that whoever the “Big Boy” is is situational based on useage.

    You can tell from the replies most repondents don’t use Statgraphics and or never seen it..  Now you’ve hit on one who does.  Check into Minitab’s and Statgraphics’ site and you will find a listing of capabilities.  Statgraphics far outguns Minitab for total statistical capabilities.  It runs with Windows like logic and is easy to use.  It is superior to Minitab in its ease to customize your charts.  What to change font or font size?  Just click on the font in the chart and it is selected and  menues pop up.  Want to change grid line colors or line thickness?  Just click on the grid line.  What a bigger chart to view, double click on the chart.  What to view all the stats in full page screen?  Double click on the stats.  Statgraphics is a stats package designed from the ground up to do stats.  Minitab is a (poor) Excel copy made up of Macros with endless add ins.  Statgraphics has SPC, DOE, Reliability stats, Anova, Hypotheses Testing, Trend Analysis, Forcasting, Six Sigma stats, Regression analysis, multivariate analysis and a hundred other functions.  I was forced to buy Minitab for our current company sisnce Ford Motors is going to six sigma, and they use Minitab.  But its interesting to note that when I was talking to their sales department Minitab’s people (themselves) told me the software doesn’t does as good a job with it’s help software as does Statgraphics.  Unless you know everything about statistics, the “Help” feature in a software package is very important.  I have both and use both.  For capability, ease of use, customizing my charts, and for the statsguide… give me Statgraphics.

    Well, its late on a Saturday night, the kids & wife are in bed and so I’ve had some time to enjoy this discussion string. Its kind of funny that every comment you made here could just as easily be describing Minitab instead of Statgraphics.
    “It runs with Windows like logic and is easy to use.” – Yup, Minitab runs with Windows-like logic and is easy to use.
    “What [SIC] to change font or font size?  Just click on the font in the chart and it is selected and  menues pop up.” — Yup, Minitab. To change the font, font size, or font color, double-click on the graph, and menues pop up. Click on the text and then click on the respective tool.
    “Want to change grid line colors or line thickness?  Just click on the grid line.” — Yup, Minitab. To change the line color, thickness, or type, double-click on the graph, and menues pop up. Click on the line and then click on the respective tool.
    “What [SIC] a bigger chart to view, double click on the chart.” — Yup, Minitab. To maximize a graph, double-click on the title bar or click on the maximize icon as you would with any Windows window.
    “What [SIC] to view all the stats in full page screen?  Double click on the stats. — Yup, Minitab. To maximize any tabular output, double-click on the title bar or click on the maximize icon as you would with any Windows window.
    “Statgraphics is a stats package designed from the ground up to do stats.” — Yup, Minitab. From their website: “Originally developed in 1972 to help professors teach basic statistics.”
    “Minitab is a (poor) Excel copy made up of Macros with endless add ins.” — Yup, Minitab’s data sheet does look much more like Excel. It even has the ability to to autofill, hide/unhide columns very much like Excel. Minitab does have a macro language – Statgraphics does not, which makes repetative actions much more difficult.
    “Statgraphics has SPC, DOE, Reliability stats, Anova, Hypotheses Testing, Trend Analysis, Forcasting, Six Sigma stats, Regression analysis, multivariate analysis and a hundred other functions.” — Yup, Minitab has these.
    “But its interesting to note that when I was talking to their sales department Minitab’s people (themselves) told me the software doesn’t does as good a job with it’s help software as does Statgraphics.” — When was that? If it was before 2000, they would have been talking about the pre-release 13 Help. Minitab’s Help system was completely revised in the current release 13. It is without a doubt the best Help system I have ever used. It is very slick. 
    “Unless you know everything about statistics, the “Help” feature in a software package is very important.” — Agreed.
    “I have both and use both.” — Same here, plus JMP.
    “For capability, ease of use, customizing my charts, and for the statsguide… give me Statgraphics.” — Yup, Minitab. For capability, ease of use, customizing my charts, and for the StatGuide . . . give me Minitab. Its kind of funny that Fred even used the name of Minitab’s post-analysis guidance tool by mistake – Statgraphics’ similar tool is called StatAdvisor.
    Don’t get me wrong, Statgraphics is a nice statistical package. Based on capability it would easily match up with Minitab, but I’ve always found its environment kind of odd. When Statgraphics for Windows Version 1 first rolled out (I was using their DOS-version at the time) it had awkward window-usage and fonts. I figured it was OK for their first attempt at a Windows version.
    I missed versions 3 & 4 of Statgrapics (switched to using JMP & Minitab), and started evaluating version 5 when my company decided to focus on Six Sigma. I was surprized to find it still has the very same odd environment and awkward use of windows in the StatFolio. And as someone else mentioned, Statgraphics does use some wild colors.

    You didn’t hit a nerve. You certainly went beyond the relm of experience into arogance whith your reference to “Big Boys” and demonstrated implictly that you do not have the flexibility to differentiate between the requirements of an applied statistician and a Six Sigma deployment.

    MBB,
    Your point is well taken. The string has wandered around with lots of people flexing their viagra induced statistical prowess. The bottom line to the original question is how it fits with the Six Sigma environment.
    If you look at the run down that Steve did in response to Fred, the real differences in terms of what a Black Belt, Master Black Belt, and/or Green Belt needs doesn’t really make any difference. I think Steve’s point was you can pretty much make any package do what you want it to do if you spend enough time with it. It is a function of user sophistication. 
    The Six Sigma environment, for the most part, is not deeply involved in some heavy statistical analysis. If it is required you can have your resident statistician happily sitting there with their “mas macho” stats package that does all the latest and greatest inovative estimates (for Mario’s benifit) run the analysis for you or you can log on to iSixSigma and lots of people seem to be willing to help out. 
    The deployments have really centered on 2 software packages – Minitab and JMP. The preponderance of deployments have used Minitab. The support is excellent and the staff will do whatever it takes to support someone who is struggling (that is from personal experience since I struggle often). Basing a software purchase for a Six Sigma deployment by pulling out your list of features and seeing who has the longest list is a pretty stupid way to satisfy your customers – YES the BB’s, MBB’s & GB’s are customers.
    As far as locating in Happy Valley – some decisions obviously can’t be made using statistics.

    It all depends what you want to do and looking for.  I tested minitab, statgraphic, jmp.  none of them is good for everything.  i use stat for QC and jmp of contour plots etc.  they all come out with new versions to improve.  so far, i like statgraphic for QC and jmp for contour plots for DoE.  From internet, you can download and test them for a month, then decide what you like.

    Don’t rely on our opinion, form your own . . .
    My number one recommendation is to download the demos and try them out for as long as necessary to get a good feel for how YOU like them. After you’ve driven the demos, you know which one is right for you.
    There are many good software applications that have the statistics/quality tools used in Six Sigma activities. These include, but are certainly not limited to:
    StatGraphics http://www.statgraphics.comMinitab http://www.minitab.com  JMP http://jmpdiscovery.com Statistica http://www.statsoft.com
    There are also a number of companies selling products based upon Excel macros.

    Trying not to push you toward, or away from, any particular software…
    Historically, SPSS has focused more on business-statistics than on industrial statistics. It is very good for social studies and survey analysis.
    On the other hand, JMP, Minitab, Statistica, and StatGraphics have tended to focus more heavily on industrial statistics. They tend to focus on tools for process assessment and improvement.
    Other packages like SAS and S-plus are fairly complex – for what I think of as professional users.
    What you REALLY need to do is create a matrix of what YOUR needs are. Do you need to analyze surveys? Do you need to run gage R&Rs? Do you need to run experiments?
    If you haven’t had training in these methods, get training before you try to select software. Your instructors will have good advice.
    Then do research on the capabilities of the software that is available. The internet can help tremendously.
    Once you’ve narrowed your needs down to a few packages (maybe four??), then download their demos and start “playing” with them.

    Do you enter the groups in two separate columns or one??
     
    Please help someone

    OK, Now I see.  First of all, Mini likes to compute her own ranges whereas you already have.  Fundamental problem I see from a technical standpoint, is that you would never make a histogram with those ranges.  If a teacher gave you this problem, he/she is not tooooo bright.  The categories should read “60-65”, “66-71”, “72-78” etc. not “60-65”, “65-70”.  If I have a value of 65, what category do I put it in?  Very basic flaw.  Each category needs to index up one.  Ok, now for your question.  I don’t know how to get Mini to accept your ranges.  But if you want to make a bar graph that looks like your data, try this:
    Put your ranges in C1 and values in C2 of a Mini Worksheet/Graph/Bar Chart/Bars Represent (Values from a table)/One column of values (Simple)/OK/Graph Variables (C2)/Categorical Value (C1)/OK
    This should give you something looking like a histogram.

    You are being far too modest.   You consistently provide well thought out and knowledgeable counsel.   (Especially for a mechanically voiced black clad hulking sociopath known to lift from the deck and choke the life out of mistake prone crew members – and of course I’m staying out of light saber range as I offer that well intended caveat…)    But it is evident that you know what you are talking about and that you always make an effort to communicate effectively.   We appreciate and learn from your continued forum engagement.

    Thanks Vinny.  I did take the VaderMobile out for a ride today and spread mayhem and destruction around the neighborhood.  Tomorrow we take VaderDog to the dog park to strike fear in the smaller and more timid canines.  I have to take my frustration out somewhere since the Forum members won’t let me.  
    BTW, I do have all the signs, placards and people lined up for our march on the Forum Headquarters if the Moderator does not free your Post.  All the Stans, Mike Carnell, Phil and even the Club Members have signed up for the Million Geek March should it come to that.  I have also ordered 10,000 decks of my cards which we will pelt the building with if our demands are not met.  Dr. Corey has agreed to be our Grand Marshall since he was an early mentor of sorts.

    I would like to request everybody to share your knowledge to me. Can sombody tell me how to forecast through regression and Gomperz model? I am not very familiar in dept with statistical model hence I would appreciate if somebody could explain step by step in a simple way. I understand only the linear regression model. What models are used for following fomulae? (1) LogTELMINUTES= -247 + 0.12 * YEAR (2) LogY= 1.8 X – 2.19, where Y is total telephone minutes and X is log GDP per capita (3) TELMINUTES= 118 * (0.006)^0.97^t. I would like to use these models but I don’t really know how.

    Hello,
    I think u r right.
    The basic thing shud be the conpatibility to the end users and ofcourse with the machine data in SS.
    I have been technical consultant on six sima solutions in India for last 5 years, I felt that statistica can be the best tool to implement for a succesful SS in any type of orgnaistaion. The good thing about it is inbuilt VB which can be implemented as per the environ ment and compantibility of the users. and ofcourse as everybody knows statistica is the reservoir of powerful analysis.

    Hello everyone,
    As I told in my earlier thread.
    Formulas and principles remain the same. Nobody dare touches them as per my knowledge. I am technical consultant for SS in India for last 5 years.
    I have seen statistica power and ability to interact with foreign data. the basic thing while implementing SS solution to any organisation is actuallly 3 points which one shud remember:
    Compatibility with your existing infrastructure, Ease of use to end-user and the last is power of analysis. I think statistica is the only solution which fits better in all apsects over any other tool in the market.
    have you ever tried Statistica QC miner , it’s awesome.

    Hi Stan,
    there r 2 things of data handling.One is spreadsheet data and another is ascii data.Which is generated thru CNC or any other machines(understanding that u know the process of production) which is also called as foreign data. These datas are same in this world atleast, I ope u r not an ALIEN.I hope I am able to update ur little knowledge. thanks

    This may well be your limited experience or maybe you are pimping Statistica. Either way what you wrote is an opinion, and defintely not a fact.

    & how did you find it? is it good / bad / indifferent? i just had a quick look & it appears to be similar to Minitab (apart from it pre-sets ‘phase’)
    don’t put yourself down, you may not be a moron – maybe just a little insecure…….

    Jaybee,
    As I said, I have not used the software.  We were shown the website and the electronic textbook during my BB training.  It has been a good resource.  I do not know of any organization that uses Statistica, but it must have some proponents as it has been around for at least 5 years.  Usually a software package that can hold up that long has to have something going for it.

    Guys, thanks a lot for the information. I have little experience using JMP and Minitab, but I used JMP a few years ago, so I  cannot compare these tools objectively.
    I am thinking of specializing in industrial statistics, but I don’t have a degree in stats/maths, just a BSc in management, MBA and a few years of strategy & ops consulting experience. Do you think a degree in statistics is necessary to do this kind of job?

       Every time I’ve applied for the job of industrial statistician I’ve noted that the fine print usually specifies a BS or an MS in statistics. If my experience in the field is at all typical, the level of work and the kinds of problems you will be expected to deal with as a industrial statistician will far exceed whatever rudimentary training in the field you may have received in your management and strategy courses.

    Ralf,
    Each software has strengthes and weaknesses.  For example, if you’re doing a six sigma project most consider Minitab the default software.  However, if you need software for manufacturing SPC, I have used SQC Pack because it does a great job with control charts (and is very inexpensive) but will not do much advanced goblygook.  Call representatives for a bunch of them and get trial software and demos and see what firs your application.

    Hello,
    As a user of 6Sigma and Minitab, the question came with a user of JMP, what is the best JMP or Minitab?
    Can someone add some arguments?

    Menno,
    You are sking something in regard to a post of mine fron about 4.5 years ago. There really isn’t an answer to your question because the programs each have strengths and weaknesses.
    This will probably get me into trouble with the JMP folks but if you have people with out much in the way of a stats background they will struggle with JMP.
    Go back and read the string. There was a lot of information in it.
    Just my opinion.
    Good luck

    Hello Mike,
    Thanks, It’s years ago, I know, still the discusion is started again within our company!
    I agree with you, after reading a lot, many programs can do the same.
    Another discusions would be more interesting.
    Kind regards, Menno

    menno,
    Just make sure who the customer is. If it is a BB training wave sit one down and watch them use it. Do the same with JMP.
    Most of these discussions are instigated by someone with a pretty heavy duty stats background. If that is the case and they think they need more power than Minitab or whatever the issue – that does not mean the entire group needs to switch. I would drive justification for whatever feature is the issue.
    Just my opinion.
    Good luck

    Menno : I can probably add a new dimension to your arguement between Minitab and Statsgraphics. You can then look at both from a different perspective.
    Spreadsheets are really heavy stats dependent. What the practitioners need for implementation is a system which takes away the stats but still deliver the results.
    Just my thoughts.

    According to my point of view
    Statgrphics is more userfriendly as compared to Minitab
    Statgraphics save time as compared to Minitab
    For SPC, SQC, Six Sigma Statgraphics is very good software as compared to Minitab
    For statistical point view especially DOE , Minitab is better as compared to Statgraphics
    i preffer Statgraphics for Six Sigma

    I have used Minitab and if that is available to you it is quite good to analyze your data.
    YOu have to purchase the rights or else you can download it for a month for free and test.
