stepwise regression

I am trying to find a way to limit the number of parameters in the stepwise option. For example, I have 40 varibles in my dataset and I would like to have a maximum of 8 variables in the stepwise model. Is it possible to do this in JMP?
Thank you,
Naama

Re: stepwise regression

In the Stepwise dialog you can click the red triangle next to "Stepwise Fit" and choose "All Possible Models". Then specify 8 for "Maximum number of terms in a model", and some larger number for "Number of best models to see". You could then sort the resulting output by AICc ascending.
