  Hi JMP Community, When building contrasts in a Regular Least Squares Fit Model analysis, the number of columns (i.e., discrete contrasts) is limited to the number of conditions (i.e., number of items produced by the combinations of all parameters). In many cases, I'd like to create more contrasts than conditions (i.e., comparisons of multiple pairs of factor combinations)  Example: VAR1 = A, B, C ...

• How to fit a model with random effect using Nonlinear platform

  May I ask a question: In “Random Effect Model.jmp”, where the response is Y, X is a fixed effect, and Z is a random effect, how to fit the corresponding model using “Nonlinear” Platform? "Example 23.13" in the book “Statistical Methods for Reliability Data, Second Edition” is an example of accelerated life test data analysis that includes random effect，I don't know how to perform the analysis, I w...

• permutation test for PLS-DA

  Hi all!  I've run a PLS-DA test for a data set that consists of FTIR spectral data of 5 different systems under 5 different treatments. I've used the fit model platform so that I could handle categorical variables in my Y variables. According to PRESS statistics, this model has an optimum number of factors of 7 and possesses good discriminating power between my samples. Then, I noticed that the st...

• Rows inclusion in PCA

  Hello,   I am running a PCA on an NMR dataset that contains some missing values. This isn't due to an error—it's simply the nature of the data, as some samples do not show certain peaks.  I have noticed that when I include these parameters Y variables in the PCA and color the score plot by sample, some samples are missing entirely from the plot. It's not consistent—some samples with missing values...
