Dear Statalisters,

If my dependent variable isn't really a COUNT measure, but an ordinal
measure of something else (in my case self assessed health status),
can I still use the Poisson estimation? What are the cons of don't
that? Why is e.g. ordinal logit or ordinal probit better?

Thanks
Tinna
You're not counting anything (e.g. number of times they were happy) so I don't think you could justify poisson. ologit or oprobit would probably be most appropriate. Or, if the assumptions of those methods are violated, you might try out gologit2 or mlogit or slogit. Long & Freese's book is good for going over these different methods:
