R Multiple Regression with Two Predictor Variables

Question

I have a data.frame (X,Y,a,b,c,d,e) Is there a package where I can predict both X and Y at the same time? Thanks for your help.

Answer 1

Try package car, ?linearHypothesis, example

a multivariate linear model for repeated-measures data
see ?OBrienKaiser for a description of the data set used in this example.

However, it might not be appropriate for the real X Y you have.
