Hello,

We've been using the xtnbreg command to look at some crime data.  Our unit
of analysis is city*day.  Some cities are much larger than others, however,
so we would like to perform a specification in which we weight the cities by
population.  We would typically do this with the pweight option, but this is
unavailable.  iweights are  possible but the standard errors are grossly
incorrect.  What can be done to compute the correct standard errors when
using the iweight option?

Thanks,
Lars
