I made a SVEM analysis and would like to use the formula to comupute process control ranges using the Design Space Profiler. I saved the prediction formula and can't save a prediction formula with process parameters, only a Mean formula here below?
Is it possible to get an expression as a function of the process parameters that can be used in the design space profiler? Or can I use the Maximum Likelihood expression reported together with SVEM in the GENREG report?
HI Victor, I tried several times cfr. below
unfortunately this does't work
Strange that, when clicking on relaunch, the expand box is emty?
Hi @frankderuyck,
Can you share your datatable or an anonymized version ? Which JMP version are you using ?
I don't understand what is not working. I reproduce the same steps on JMP dataset Powder Metallurgy with a Weibull SVEM Forward regression. I have only the option "Save Resample Formulas" like you have, and it gives me a Pred Formula similar to what you showed :
Do you have also the column property "Expand Intermediates" with the value set at 1 ?
When I launch the Profiler from the Graph menu with the "Expand Intermediate Formulas" :
I obtain a Profiler with the response linked only to the predictors :
You can check you have the same settings as I show here (on JMP version 18.1.2 for me), and if it's not helpful, can you share a dataset so that I can try to see what's not working ?
Best,
Ok, I understand better.
Some of the "Purity sample prediction formula" in the Profiler corresponds to constant values. These 24 sample predictions values are constant, so they don't have influence when you change factor settings.
Example with Purity Sample 11 Prediction Formula :
What I would suggest is to replace these constant values predictions formula by their values in the Pred Formula Purity SVEM formula, so that the Profiler only includes prediction formulas linked to factors. With the option "Expand Intermediate Formulas" checked with this simplified formula, it should work :
Please find attached your datatable with the added simplified SVEM formula column and a script with the final Profiler.
