Multiple regression new variable

tourniquet — Wed, 30 May 2018 14:57:00 GMT

Hi everyone.
I want to look at my thesis model using several regressions in three steps. I know there are programs where you can do the whole model in one step, but I am not at that level.
Basically the first step is want to do a multiple regression with three IV and 1 DV. The effects of the IV's on the DV will be the new IV in a multivariate analysis, and the third step will be another muliple regression.

My question is: how do I save the restults from the first multiple regression and use it as a new variable? I am sorry if this is super basic, but I would really appreciate some help!

I assume that you know how to make a JMP data table and enter the data. I will call the three independent variables X1-X3 and the dependent variable Y.

Select Analyze > Fit Model.
Select column Y and click Y.
Select columns X1 through X3 and click Add.
Click Run.
Click the red triangle at the top left and select Save Columns > Prediction Formula.

Now you will have a new column, Pred Y in the data table. You can use it like any variable at this point.
