RE: st: can GLLAMM handle missing data?

Hi Nick,
Thanks for your reply. Apologies for such a simple question but I am new to GLLAMM and I was just surprised that the output states:
number of level 1 units = 2284
number of level 2 units = 566
these figures reflect the sample size for those respondents who have data on at least 1 data point, which is why I assumed it included them all rather than just those with complete cases on all time points.
If it does remove missing data, would it do it listwise? How can I find out how many cases are included in the analysis?
Thanks,
Francesca

What would "handle" mean here? It's my guess that -gllamm- (SSC, etc.) handles missing values just like any similar command, by setting them on one side. How could it be otherwise?
