Thanks a lot to Kit Baum, a new program -grcompare- (as an on-going project) is now available from SSC. This is a Stata module to make group comparisons in binary regression models using alternative measures, including
gradip: average difference in predicted probabilities over a range
grdiame:difference in group averaged marginal effects
grdidip:difference in difference in predicted probabilities
grdigap:difference in group averaged predicted probabilities
grmarg: (local) marginal effects and difference in marginal effects
For these programs to run well, you need to install SPost first as the grcompare module use some low utility programs from SPost (net search SPost) for Stata 9 (spost9_ado). While installing SPost, you need to be aware that there could be variations across different versions. More recent versions of SPost may work well with grcompare, but the author of grcompare has not systematically tested yet.
If you are interested in technical details, please send an email to [email protected] for a methods paper that covers these measures and their statistical inferences.
