Different mixture experiment analysis results JMP 17 & 18

[#1]

Did something in JMP 18 change in analysis of mixture experiment results. Below is shown that analysis results from exactly the same DOE data sets are different

1. DOE three component mixture

2. DOE three mixture components + one process effect

In JMP 18 analysis above the model is different!

What has changed and why? Remark: despite of different plots & model graphs of JMP 17 - 18 prediction profilers are identical.

I'm not sure the correct word is accurate...different, yes.  It appears the JMP18 version looks more like a leverage plot than the one from JMP17.  Typically those plots are narrowest in the center and expand near the ends.  Collinearity is typically a cluster of points near the middle.

The DOE analysis script is 100% reproducible both in JMP 17 and 18.  When running second DOE (mixture + process effect) analysis script, developed in jmp 17, in jmp 18 besides the prediction plot also model is different (?) The prediction profilers always are equal.

Yes, but in your initial post, the statistics were different as well. That does not appear to be a JMP issue.

As in case 1 the case 2 data set and analysis script are exactly the same, indeed now results are also different..

Only difference is the two jmp versions
