Nora -
I just read your email again and had a new thought - if your correlation
is within families, shouldn't your i() be the family var not the id var?
You'd specify the id var with a model that has repeated measures on
the same individuals, but in your case if your panels are families
instead of individuals, you probably want i(famvar). I would bet that
is where your error message is coming from.

dear statalisters,
i have to run a logistic regression that has to take into account
clustering of subjects into families.
the command 'logistic' works but does not account for clustering, so the
standard errors are smaller that they should be.
i am trying to use on the same dataset the command xtgee:
xtgee dep_var indep_var, family(binomial) link(logit) i(id)
but invariably i get this response from stata:
estimates diverging (absolute correlation > 1)
r(430);
should I rearrange the data somehow in order to run ‘xtgee’? it was my
understanding that xtgee does not need to ‘tsset’
can anyone help me with this issue?
thanks a lot!
