Raffaella <raffaella_00@yahoo.com> asks whether Stata requires balanced
panels to fit nested logit models.

The -nlogit- command does not work with panel data. I suspect that Raffaella
is getting an error message like:

		unbalanced data
  		r(459);

The improved version of the -nlogit- command works with unbalanced data (not
with panel data). This change to
-nlogit- was part of the  17jun2005 update to Stata 9.
