RE: st: margins

["Ozturk, Orgul" <odozturk@moore.sc.edu>]

Sorry about that
Following works: 

reg logrealwagechange i.promCurrentJob##i.woman#i.govt## i.schoolinggroup $extras $changeindustryvars $changeoccupations  if careerstage==1
margins, at(woman=1 ) at(woman=0 ) over (govt schoolinggroup promCurrentJob) post
margins, coeflegend

and then I run test in the following form
lincom	_b[1._at#0.schoolinggroup#0.govt#0.promCurrentJob]-_b[2._at#1.careerstage#0.schoolinggroup#0.govt#0.promCurrentJob]


reg logrealwagechange i.promCurrentJob##i.woman#i.govt## i.schoolinggroup $extras $changeindustryvars $changeoccupations  if careerstage==1
margins, at(promCurrentJob =1 ) at(promCurrentJob =0 ) over (govt schoolinggroup woman) post
margins, coeflegend

this does not work:

reg logrealwagechange i.promCurrentJob##i.woman#i.govt## i.schoolinggroup $extras $industry $occupationgroup  if careerstage==1, noc
margins, at(woman=1 ) at(woman=0 ) over (govt schoolinggroup promCurrentJob) post
margins, coeflegend


and this is what I have for the xtlogit, fe 

xtlogit promCurrentJob i.woman##i.careerstage##i.govt##i.schoolinggroup $usualsuspects, fe
margins, at(woman=0 ) at(woman=1 ) predict(pu0) over (careerstage schoolinggroup govt) post

again this does not really work.

Thank you very much..
I can send you the data and the do file if you need.

And your -margins- command is...
And the _exact_ contents of your macros is...

We cannot help you if you do not give the necessary information.

Even if I get these I am not perfectly sure how to interpret them.

Once again, _exact_ commands please.
