good evening
I have ru a series of logistic regressions, ignoring the fact that the
subjects were fron different organizations
What I would like to do now is to see if there are any organizational
effects
Can this be done using xtlogit , I also need to xi:
So the command would be xi: xtlogit y i.x1 i.x2 etc , i(organization)
If it is correct to use xtlogit and I would also be interested in the
associated odds ratios, in the output you get a value for rho, is this
the level of variation between organizations and if so how can I tell if
there is an organizational effect and what effect this may be having on
the individual odds ratios
Regards
ann
