Hi,
I want to compare the effect of one variable (var1) on dependent variable across two subgroups (e.g. female and male).
One way is to run the same regression model separately for each group and test the differences between these two
groups using suest.
Another way is to run the regression model including the interaction term (var1*sex).
Which one we should use? or both? Thanks very much for input.
Best regards,
