Stata/MP 14.2. No access to internet.

My data is longitudinal, with 128 individuals and around 700 consecutive daily observations per individual. There can be many zeros per individual or there might be many non-zero outcomes, just depends on the case.

How can I compare the goodness of fit of two nested models fitted with clogit with robust or clustered standard errors?

lrtest is not an option according to Stata.

I have found nothing on the internet or in the documentation.
