Comparing coefficients across DRs

[RACHNA PRAKASH]

I run doubly robust regressions after running PSMatch2 on two different samples. I would like to compare the regressions coefficients across the two DRs. When I try to store the coefficients to compare them using est store, STATA tells me 'last estimation not found.' I can't run a fully interacted model using # with DR. Is there a good way to compare the coefficients across the two DR estimates? Thanks so much.
