Hello,

I am using JMP 13 and I can not seem to find a way to automaticaly evaluate my model's accuracy on the holdout set. I am buliding a linear regression model.

So I would like to preserve the model (with the contained effects and estimates sizes), which was bulit on the training set, but calculate accuracy predictors (R^2, R^2 adjusted and RMSE) on the holdout set. In the moment the only solution I found is to calculate RMSE "by hand", since you can calculate the residuals. Is there any way to do this automaticaly?

This seems such a basic operation for model buliding process so I am quite sure there should be some good option.

Thank you for your help,

Danijel
