  • Are power caldualtions in mixture experiments reliable?

    In a ternary 12-run mixture experiment using a special Sheffé model I get only 5% power of the compnents; this means 95% chance that component effect can't be observed? Are power calculations in mixture experiments reliable taking into account high collinearity among factors?

  • Simulate vs Bootstrap methods in JMP: which to use when and why

    Hi All,   I'm hoping someone from JMP might be able to provide an explanation as the the differences/similarities of the Simulate vs Bootstrap approaches when evaluating model estimates. (JMP Pro)   Some links to previous Discovery Summit presentations from Gotwalt and others can be found here, here, and here. One clear difference between the methods is that Simulate requires you to swap out a col...

  • Mixture-Process Design or Response Surface Design

    Hello everyone,   I am writing to ask for advice on designing an experiment to optimize a somewhat complicated chemical reaction. Here is what it involves: A substrate (1.0 eq) reacts with a mixture of two reagents called RA and RB. The total amount of RA and RB is always 0.5 eq. The proportions of RA and RB vary within the mixture of these two reactants.
    RA varies from 38% to 62%, and RB also vari...

  • How to subtract a variability from regression

    Hello everyone, I’m learning regression and have some questions about variability. Suppose I want to study the impact of a factor X on a process response Y. The regression results suggest that moving from condition level A to B of X changes Y by about 10%. However, I also know that the process itself has variability — for example, even at the same condition level of X, Y might fluctuate by around ...

  • difference in EFFECT TESTS between Generalized regression and Fit Least Squares platforms

    I'm on JMP Pro 18.2.2 and have noticed that the Effect Test table differs substantially between the Generalized Regression platform and Fit Least squares (and also all other platforms in JMP) when there is an interaction term.  This is true even when the design is perfectly balanced.  The Generalized Regression platform generates sums of squares that depend on the parameterization of the factors. ...

  • Disallowed combinations

    Hello, I have a factor with three levels and I am trying to create a design in which this factor levels are not equal in any given block. So for instance, Factor A should not have the same level repeated in any block. How can I do this please? Thanks.

  • Power Explorer for Two Independent Sample Equivalence

    Does anyone have a case study of the use of the Power Explorer for Two Independent Sample Equivalence?   Ideally, the case study would demonstrate it's use for scale-up from future pilot line trials to eventual full production.     I ask this because there doesn't seem to be an example and/or sample data file on this subject in the JMP Help.

    I have used the interval explorer for parametric reliability life test planning for sample size calculation of accelerated life test. Please can someone confirm if the sample size returned is the total sample size or sample size per stress levels? Assuming I have 3 temperature levels, do I use 75 samples per temperature level or 25?
