Hi all,
I'm working with a discrete-time survival model, and I have doubts
about how to use weight (pweights) in a person-period data. I did the
following:

logit  nevent  d4-d18 [pw=exp], nolog nocons

Is it correct?
exp is sampling weight, inverse of the probability that the
observation is included because of the sampling design. When I use
pweights I have problem with lrtest too, because I have to "force" the
process.


Does somebody have a advice or recommendation about it?
Thank you.
Regards.
