RE: st: mi estimate using gllamm and pweight

["Wike, Traci" <twike@email.unc.edu>]

thanks, Richard.  the error message states: probability weight variables not found.
I feel like it has something to do with how the weight is defined. I just can't figure out how to do it differently.

Are you getting an error message, or do you get the same results both
with and without weights, or what? It isn't clear what the problem
is. Above you have a space -- pweight (psb) -- if that is what you
actually typed you may need to delete the space. The help for gllamm
provides some additional details about how to use pweights -- it
sounds like gllamm makes you do a bit more work than most Stata commands.
