Re: st: question on gllamm (multilevel logit)
Well a number of strange things may be happening with your model specification and your data... Check that you don't have underidentified model (in other words, that you are not estimating the same constant or same slope twice); and check that you have the most recent version of -gllamm- and all the required programs (see gllamm.org). Without any further information, nobody on this list will be able to help you -- Nick Cox FAQ makes all sorts of suggestions as to what should be included in your posting.
