-mfx compute- will compute the marginal effects after -xtlogit, fe- with the predict(pu0) option. The pu0 comes from -clogit- which also estimates conditional fixed-effects logit models. I am not sure why "no effect" is reported when using the -predict(p)- option. . webuse union (NLS Women 14-24 in 1968) . qui xtlogit union age grade south year, fe i(id) . mfx compute, predict(pu0) nose Marginal effects after clogit y = Pr(union|fixed effect is 0) (predict, pu0) = .16861097 ------------------------------------------------------------------------------- variable | dy/dx X ---------------------------------+--------------------------------------------- age | .0106352 30.538 grade | .0120169 12.7934 south*| -.099099 .381388 year | -.0083177 79.6184 ------------------------------------------------------------------------------- (*) dy/dx is for discrete change of dummy variable from 0 to 1 . mfx compute, predict(p) nose Marginal effects after clogit y = Pr(union|single outcome w/i idcode) (predict, p) = 1 ------------------------------------------------------------------------------- variable | dy/dx X ---------------------------------+--------------------------------------------- age | (no effect) 30.538 grade | (no effect) 12.7934 south*| (no effect) .381388 year | (no effect) 79.6184 ------------------------------------------------------------------------------- (*) dy/dx is for discrete change of dummy variable from 0 to 1 Hope this helps, Scott ----- Original Message ----- From: "Bo MacInnis" <bmacinni@pacbell.net> To: <statalist@hsphsun2.harvard.edu> Sent: Tuesday, March 02, 2004 6:54 PM Subject: st: How to calculate marginal effects after xtlogit, fe? > Hi, > > Would anyone help me to calculate the marginal effect of a binary regressor > after I estimate a fixed effect conditional logit?
