Hi, Statalisters.

I'm looking for a method to handle clustering on two factors: repeat binary measures from individuals who are in small groups.

I can use -xtgee- to handle clustering by individual, but it seems that it'll only handle one level of nesting. But how to handle the potential correlation between group members? Upon trying a simulation of the data I anticipate collecting there won't be sufficient variation to use -gllamm-. And I'm not really wanting to understand the variance contributed by those groups, just to account for it. Any suggestions? Thanks!
