I accidentally posted this in "Homework Help," my apologies:
I have data from two samples, different N's, who took the same measures. We ran hierarchical regressions for each sample with multiple predictors in each step. I am wondering whether there is any way to compare the percent variance accounted for at each step for the two samples (e.g., did the predictors in step 2 of each sample's regression account for significantly different amounts of variance)? Many thanks for your help.
