Hi all,
I've developed a logit model to be applied to three different sets of cross-sectional data(the same model specification with differenet samples). What I'm trying to uncover is whether there are changes in the substantive effect of a given independent variable (IV) on the dependent variable (DV) controlling for other explanations at different times and across time.
My questions are1)How do I assess increased / decreased size in the association between the IV and DV? (2) Can I simply look at the different magnitudes of the coefficients across the models ?
