Re: st: SAS versus Stata, Panel Study Logit models

Alas, this does not mean anything to me, but apparently this is
something SAS and SPSS think should be done by default whereas Stata
does not. Who is right? And if I were so inclined, is there an
option I could use in Stata that would do this adjustment?
One more tidbit: digging around the SPSS documentation, I found
"By default, the procedure will adjust the correlation estimates by
the number of nonredundant parameters. Removing this adjustment may
be desirable if you want the estimates to be invariant to
subject-level replication changes in the data. "
This still doesn't mean much to me, but apparently Stata thinks it is
better for the estimates to be invariant to subject-level replication
changes in the data? But if I disagree with Stata and want to do it
like SAS and SPSS do by default, am I out of luck?
