Hi all, 
   I'm trying to use the new ssm wrapper (Stata
Journal (2006), 6, 3, pp. 285-308) to fit a logit
model with a single endogenous dummy. The model does
not work when I include population weights (although
it should: p.292), but works when I do not. Here's the
model and the error message:


ssm emoprobb age harassd puberty11 firstvi ktouch
usborn2 if xf==1 [pweight=rweight], s(harassd = age
edimp milserved) adapt q(16)  family(binom)
link(logit)

; invalid name
r(198);

Again, the same model runs properly when I remove the
population weights. Any help would be greatly
appreciated. Thanks.
