Dear Statlist,

I'm having a problem with the gllamm program (family(binomial) link(logit)).

1. My dependant variable (a proportion) will only work if the variable contains a zero, otherwise I get an r(2000) (no observations) error

2. Adding binary explanatory variables (eg a health variable where 1 excellent, 0 not excellent) results in the message 'variables have been dropped, can't continue' and an r(198) error. The null model works; the null model works with continuous variables added in; the null model plus one or more binary variables fails.

The command I am using is     gllamm  [depvar] [varlist], i(ParticipantId) family(binomial) link(logit). I have 276 cases and 129 variables (not all of which are added to the model).

If anyone with experience of gllamm has an idea of what is happening here, I would be most grateful to hear it. 

Thank you!

Alice Dalton
