using -gllamm- command?


Roger Harbord and Alexander Staus have already given some advice about the
greater generality of -gllamm-.  Let me just add that, when you're working
with these nonlinear models, you'll want to use *adaptive* Gauss-Hermite
quadrature.  -xtlogit- and -gllamm- use different implementations of
adaptive Gauss-Hermite quadrature.  As I recall (the posts are on the List
within the past year), -gllamm-'s implementation is somewhat slower but more
accurate than -xtlogit-'s.  StataCorp was looking into this matter at last
