Dear all, I hope you would not mind my beginner question and could help me out of this problem or I will have to manually loop it myself. T_T My sitution is that I have 10 independent (e.g. A,B,C,D,E,F,G,H,I,J, I will call them "AtoJ") variables and 1 dependent variable, my task is to run regressions of different combination of independent variables. The combinations are, taking away one independent variable at a time, and run 10 regression, so the first one will be "AtoJ-A", then "AtoJ-B", "AtoJ-C" and so on. Then I will have to take two indepentdent variable at a time, so "AtoJ-AB", "AtoJ-AC" and "AtoJ-AD" and so on. (How many regressions do I have to run for that?) I have two questions, Firstly, how to do that as in what command I should be using? Secondly, I want to be able to see the result of the regressions, not only the estimators, but also t-stat, F-stat(anova), test of normailty and VIF. Is that possible? Thanks in advance for your kind support, I hope I have expressed my situation clearly. Bryan
