I'm using minitab 17's stepwise regression, and it's generated a model I'm satisfied with (strong predicted R^2, etc...). I then want to use that stored model to generate predictions for ~1000 additional observations. However, I'm having trouble loading those additional observations without losing the stored model?

Does anyone have an idea how to do this? The documentation for the predict feature is extremely sparse. I'm considering copy-pasting the model into excel and coding the predictions there, but that would be extremely time consuming due to the number of interaction factors I'm working with.

Ideas? Helpful documentation I'm missing?

Thanks.
