be notified via email.The complete statement in the book about Statistics and Minitab is
- the upper bound is 0.492 gram for the standard deviation (given by the chi-square method). This means that 95% of the hamburgers have fat content with a standard deviation that is lower than 0.492 gram.

Fausto GalettoParticipant@fausto.galetto Include @fausto.galetto in your post and this person will
be notified via email.I try to see IF I understand correctly your statements.
You say:
- · “The wider the net you cast, the more often you’ll observe the true value.”
Do you mean that the “true value” is an observable quantity?
You say:
- · There are cases where a confidence interval (Frequentist statistics) can also be equal to a credible interval (Bayesian statistics), and the statement would be correct.
Do you mean that the statement “95% of the hamburgers have fat content with a standard deviation that is lower than 0.492 gram.” is correct only IF a credible interval is used (Bayesian statistics) AND confidence interval=credible interval, while it is wrong when we use “Frequency statistics” OR confidence interval is NOT=credible interval?
Thank you

1. The sample S1 (sample size 100) is 10% of the “population”? It seems so from your writing…
2. The sample S2 (sample size 10) is 10% of the SAMPLE S1? It seems so from your writing…
3. IF NOT specify clearly
After your reply, you can have “your solution”…
Btw: Quality score : 10/100 = 90% is misleading; it must be written 90%=[(100-10)/100]*100

@rbutlerSB was the first to reply ; perhaps he wants to be
- · The last straw that breaks the camel back………..
AS SAID by @rbutlerSB
- · Ignorance, Incompetence and Presumptuousness is very present in this thread
- · Because from his Universe of KNOWLEDGE @rbutlerSB is UNCAPABLE to
- · REALISE that Minitab T Charts are WRONG
- · Being T Charts based on the “WRONG theory” of the paper “E. Santiago, J. Smith, Control charts based on the Exponential Distribution, Quality Engineering, 25:2, 85-96, at the link: https://www.tandfonline.com/doi/abs/10.1080/08982112.2012.740646”
- · which has wrong formulae for the Control Limits of T Charts
- · in spite that is was “Peer Reviewed” and “Published in a GOOD Journal” (so having the dignity to be considered “scientific”)
@rbutlerSB DOES NOT accept to STUDY and to SEE IF I AM right!!!!!!!!!!!!!!
He prefers waffling as follows:
- · “””””””””As the most prolific responder to his posts I’ve tried to politely point out the shortcomings of his theory and why it isn’t viable. It has been, as I thought it probably would be, a vain effort. The only thing I’ve received in return is a barrage of ad hominem attacks and multiple accusation of waffling (6 times) (to waffle – to be unable to make a decision, to talk a lot without giving any useful information or answers). Waffling – back at you OP.””””””
- · “””””””””There really isn’t anything else to say – the OP has constructed a theory based on postulates and axioms of his choosing. He has reported the results of his theory as though they were correct while the empirical evidence he himself has compiled in this regard says otherwise, he has provided no proof of the correctness of his theory, and he reacts violently to any suggestion that his theory is wrong. I’m sure the OP will want to have the last word, as well as the one following that – go for it Fausto – QED (Quite Enough Discussion) “””””””””
- 1. I ASKED @rbutlerSB and others to PROVIDE where I CAN FIND their PEER REVIEWED papers!!!
- 2. They DID NOT let me read their PEER REVIEWED papers!!!
- 3. THEY realise that I will find THEIR errors (IF there are any….) USING THEORY
- 4. Certified MBB and (Bio)Statisticians SHOULD know THEORY (Probability, Statistics, Logic, ….)
Deming’s ideas are in order [Deming (1986)]
- · “It is a hazard to copy”,
- · “It is necessary to understand the theory of what one wishes to do or to make.”
- · “The result is that hundreds of people are learning what is wrong. I make this statement on the basis of experience, seeing every day the devastating effects of incompetent teaching and faulty applications.”
The WAFFLERS are UNABLE to understand that the attached figure (to my Previous reply) is TWICE WRONG!!!!!!!!!!!!

From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 13.6 pots per day were sold with a Standard Deviation of 0.7 pots.

be notified via email.Your last reply with the statement about “”””the PBV method of scientific discourse (Proof By Volume)””” made me think that we have different ideas about THEORY and SCIENTIFICNESS.
For me THEORY is
- · The set of all LOGIC Deductions
- · Drawn
- · From Axioms and Postulates
- · Which allow to go LOGICALLY from Hypotheses to Theses
- · Such that ALL Intelligent and Sensible people CAN DRAW the SAME RESUL
People who do not know Theory have to be considered IGNORANT
People who are IGNORANT and waffle about subject they do not know have to be considered PRESUMPTUOUS- · ALL my papers and books are BASED on THEORY!!!!!!!!!
Let’s see
1. IF YOU applied THEORY
2. In your replies
3. Some times…
The subject of the post was and is CONTROL CHARTS (with NON-Normal data)
- · CERTIFIED MASTER Black Belts should know it!!!!!!!!!!!!!!!!
- · STATISTICIANS, “””expert””” of Six Sigma should know it!!!!!!!!!!!!!!!!
Your first reply on December 7, 2019
- · was NOT based on THEORY
- · but only on your ideas (shared by many others) that one has “””submit … to a peer reviewed journal”””
- · because you did not have the faintest idea how to deal with the Montgomery case….
Your second reply on January 10, 2020 (one month later!)
- · was AGAIN NOT based on THEORY
- · but only on your ideas
- · “”””I agree nobody, including yourself, tried to solve the cases. As I’m sure others will tell you, the usual procedure on this site is for you to try to solve the problem, post a reasonable summary of your efforts on a thread and then ask for help/suggestions.”””
- · and ASKING me to “”””learn about G and T charts, and do the work manually”””
- · because you did not have the faintest idea how to deal with the Montgomery case….
The suggestion of @Darth was the hint for my document “””Open-Letter-for-Master-Black-Belts”””
@Darth uploaded the T Chart made by MINITAB SoftwareThat was a great advance, BECAUSE it showed that MINITAB T Chart WERE and ARE WRONG.
Your third reply on January 14, 2020
- · was AGAIN NOT based on THEORY
- · but only on your Super_Long_WAFFLING
- · and on your ideas (shared by many others) about AGAIN “””peer reviewed”””
- · by saying “”””””Given the bombast I decided to see what I could find. I couldn’t find a single peer reviewed paper by the OP listed in either Pubmed or Jstor.””””””
- · and after “”””””I also know many of the statisticians at Minitab have numerous papers in the peer-reviewed press on statistics and process control and have made presentations at more technical meetings than I could list. Under those circumstances, if the OP really thinks he is right and Minitab is wrong then the OP first needs to take the time to find, and thoroughly understand, the theory behind the T chart – this would require actually researching the topic – books, peer reviewed papers, etc.””””””
- · because you did not have the faintest idea how to deal with the Montgomery case….
AGAIN and AGAIN and AGAIN and AGAIN………..PEER REVIEW!!!!!!!!!!!!!!!

THIS have been really the best advance in the discussion!!!!!!!!!!!!!!
IT proved CLEARLY that “”””PEER Review”””” DOES NOT ASSURE Quality of papers!!!!!!!!!!!!!!!!!!
As a matter of fact
- · The paper of J. Smith “””Control Charts Based on the Exponential Distribution“””
- · Written by MINITAB “””Experts (???)”””
- · PUBLISHED in the PRESTIGIOUS Journal Quality Engineering

David007 replies from January 27, 2020 to January 30

- · BECAUSE he did not and does not know THEORY
- · by writing “””””The T chart (Exponential) doesn’t show OOC but MR does if you use Non Normal Capability Six Pack (Exponential)”””””·
- again NO THEORY, only BLIND use of Minitab [Six Pack is another drawback of MINITAB
- · and many other NONSENSE

Let’s recap the story (IF you want to read it) and see the increasing grade of goad….:
- 1. January 27, 2020 at 6:41 am #245779REPLY New account, old timer chiming in. (omissis) With n=20, distribution fitting and parameter estimation isn’t going to be very accurate, but it can still be useful. In my experience using automated …. Also for t charts in Minitab you can choose Weibull or Exponential. Personally I think … t charts got their popularity boost on health care as a simple approximate way to deal with their non normal data. There is no “hidden theory”. Joel Smith has a good paper on t charts …Control charts for Nonnormal data are well documented. (omissis)
- 2. January 27, 2020 at 10:00 am #245789REPLY ….it’s in Quality Engineering “Control Charts Based on the Exponential Distribution…” Quality Engineering, Volume 25, 2013 – Issue 2 https://www.tandfonline.com/doi/abs/10.1080/08982112.2012.740646 (omissis) Is your issue that the data is neither exponential nor Weibull, but something else? How can you tell with n=20?
- 3. January 27, 2020 at 12:24 pm #245798REPLY The exponential T charts use an exponential distribution and use maximum likelihood to solve the parameter. This is exactly equivalent to the control chart obtained when doing a Nonnormal capability six pack with an exponential distribution. Minitab didn’t invent the T charts. They became popular in health care so they added the tool. If you are saying the chart fails to detect assignable causes, try simulating some exponential data.
- 4. January 27, 2020 at 2:25 pm #245800REPLY The T chart (Exponential) doesn’t show OOC but MR does if you use Non Normal Capability Six Pack (Exponential) PS In order to determine if a method is correct or not correct you need to do thousands of simulations, and look at alpha. Add power study then even more.
- 5. January 27, 2020 at 2:53 pm#245801REPLY According to the Distribution ID method, we should be using a 2 parameter exponential or 3 parameter Weibull anyway. But as I’ve repeatedly said with n=20 the model is going to be wrong anyway.
- 6. January 27, 2020 at 2:57 pm#245802REPLY You really should play with some simulated exponential data. You’ll be surprised by what you see as “inherent variation”
- 7. January 30, 2020 at 11:19 am #245873REPLY Post a white paper to prove your point.
- 8. February 2, 2020 at 4:27 pm #245904REPLY Minitab tech support is not needed. Calculate the scale (Exponential) or scale and shape (Weibull) using maximum likelihood. Compute .135 and 99.865 percentiles.
- 9. February 3, 2020 at 6:08 am #245935REPLY As others have said, I anxiously await to see your rebuttal paper in any of Quality Engineering, Journal of Quality Technology, Technometrics, Journal of Applied Statistics, etc.

The fact that according to Science News for 24 May 2019, the proof of the Riemann Hypothesis (or conjecture) is still in doubt does not mean that it was not proved.
It means that the “experts” on the matter did not acknowledge it.
BTW. How many people do you know that publically wrote that they made a stupid error?
You wrote lastly:
<p style=”text-align: center;”>It’s nice that Juran praised one of your papers at a symposium – the big question is this – which peer reviewed journal published the work?</p>
Before being asked to enter Politecnico of Turin, I worked for more than 20 years as Quality Director in Corporations AND I had to prevent problems NOT to think to write for Peer Reviewed Journals; my papers were presented to International Conferences.
Since you insist on Peer Review, please find a paper of mine, presented in 2006…
I am looking for SOLUTIONS by MBB who are used to use extensively Minitab, JMP, SixPack, SPSS, … AND I am sure about my method: it follows Probability Laws, Statistics, Mathematics and LOGIC!

9. The OP then slams me for stating he hasn’t tried to solve the cases. OK, fine, I’ll assume he did try. I probably should have said the OP hadn’t tried to do any research with respect to finding the theory of T control charts or really understanding anything about them other than insist Minitab drop everything and get back to him with the demanded information pronto! – but this really doesn’t matter because, as one can see in the other posts, the OP KNOWS Minitab is wrong because he has a proof based on THEORY! What theory he doesn’t say but apparently it doesn’t matter since this THEORY is better than the THEORY of T Charts – even though, by his own admission, he doesn’t know what that theory is.
As I told you before you did not read carefully my documents.
There it is said where to find the THEORY that proves Minitab being wrong!
I am still waiting for Minitab reply

be notified via email.SINCE 1982 my students had the THEORY to solve the two Cases.
SINCE 1982….
Since then THOUSANDS of MASTER Black Belts have been unable to solve the cases.
Deming : “It is a hazard to copy”. “It is necessary to understand the theory of what one wishes to do or to make”. “Without theory, experience has no meaning”. “A figure without a theory tells nothing”. «The result is that hundreds of people are learning what is wrong. I make this statement on the basis of experience, seeing every day the devastating effects of incompetent teaching and faulty applications» and Galetto (Quality of methods for quality is important, EOQC Conference, Vienna, 1989) have been very clear about the need of being scientific in Quality Management and decisions. J. Juran praised F. Galetto’s paper during his presentation at Vienna Conference.

“”””I agree nobody, including yourself, tried to solve the cases. As I’m sure others will tell you, the usual procedure on this site is for you to try to solve the problem, post a reasonable summary of your efforts on a thread and then ask for help/suggestions.””””
In the Fausto Galetto’s two documents there is the solution, based on THEORY!!!
