st: share dependent nested logit??

["Derek Chong" <derek.chong@rmit.edu.au>]

hi all,

does anybody know how to estimate a nested logit with
shares/proportions as the dependent variables ie a nested logit using
GLS? if not is there another package that can do this?  sorry if this
has been asked before i am new to the list.

thankyou

Derek
