  • 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. ...

    hello all, I am struggling with the low R2 and R2 adjusted i am getting from the model generated by JMP. every reading has many replicates but the R2 is still low (0.17). i did Box-Cox transformation based on the suggested λ but still R2 very low. any help on how to improve the R2? and what does low R2 mean?? I am really stuck and cant trust my statistical results on which factor is significantly ...

  • 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.

  • Encoding of categorical variables

    Hi everyone, I'm interested in an *easy* recoding of categorical variables in JMP. Depending on the variables I want to do this to be able to specify which levels should be compared to each other. If I include all levels in the model I want to get p-values for exactly the differences I want to see or I want to do a model selection and just include certain differences of levels. In these cases the ...

  • Sample size for Reliability Life Test

    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?
