  •   The partial derivatives of the expression  Y = 2*X1 +3*X2^2  with respect to X1 and X2 are:
     dY/dX1 = 2
     dY/dX2 = 6*X2
     so if we plug these values into the equation you are using for the standard deviation of Y this would be
      sqrt( (2*.1)^2 +(6*3*.2)^2) = 3.606

      On the other hand MBB is skewed 13,2,2
      whereas
      PhD is a nice distribution as well as a geometric progression 16,8,4

  • Binomail?  Well, thanks for the recommendation but where I live the postman just delivers the stuff unasked – I’ve never had to purchase mail from him.

    The script for the Monty Python skit “Argument Clinic” probably qualifies:
    “Is this where I can have an argument?”
    “I told you once.”
    “No you didn’t”
    “Yes, I did.”
    “You most certainly did not.”
    …etc.
      I’m sure you can find the entire script somewhere on the net – check Google.

  • clb1 replied to the topic Need a sigma. in the forum General 12 years, 10 months ago

      Sigmas are sold in matched sets of 6.  If he only has 5 for sale then you are looking either at remaindered/seconds stock or matieral that has suffered damage in transit.. If the lack of 6 is due to shipping damage then the quality/integrity of the remaining 5 is doubtful
      If it is truly remaindered then hidden damage shouldn’t be an issue and…[Read more]

  • Chinese?????  Sorry no.  It’s a Taguchi design.  The inner array defines the way the characters are combined/pitted with/against one another and the outer array consists of the possible scenario combinations.  Rumor has it that the concept for combining actors and plots in this fashion grew out of one of those legendary after hours tequila fests…[Read more]

  • clb1 replied to the topic Data in the forum General 12 years, 11 months ago

    The first problem is the fact that you have analyzed data.  Data that has been analyzed is no longer raw data.  Analyzing analyzed data is akin to re-cooking a meal and the results will be pretty much what one would expect after such an effort.  (This is much like the problem of what to do with ground water.  Water that has been ground, usu…[Read more]

    The really good quality slogan sites don’t have any.

  • clb1 replied to the topic Six sigma in the forum General 12 years, 11 months ago

        I guess using “What” as a standard for comparison is a reasonable choice.  Personally I prefer “Why” because it is shorter (in terms of letter count) and it has the ring of authority.  “What” on the other hand, can easily be misinterpreted to mean nothing more than the fact that your hearing was impaired and you didn’t understand the stateme…[Read more]

  • clb1 replied to the topic cross-over in the forum General 13 years, 1 month ago

     If you already know about crossover designs and you know what they are used for then you know who uses them and why.  Sit down with your advisor and ask him/her what you should do.  If he/she is fresh out of ideas then get over to the local hospital and see if you can start a project with one of the doctors.

  • clb1 replied to the topic cross-over in the forum General 13 years, 1 month ago

    Try Google – “crossover design” gives 556,000 hits or so.  The top ten look like they might get you started.

  • clb1 replied to the topic statistical thinking in the forum General 13 years, 3 months ago

       Data with an example is much more difficult to deal with than data without an example.  Data that is free of examples is data that is clean.  Clean data is certain data, therefore any conclusions one might draw from such data are absolute and without error.  However, if there are one or more examples in the data then the only way you can hope…[Read more]
