st: How to refer to results from three mlogit models in a single predictnl command

[Gerald Manthalu <gmanthalu@hotmail.co.uk>]

Hi Statalist,

I am estimating and saving three mlogit models as follows

mlogit y x1 x2

eststo m1

mlogit y2 x1 x2

eststo m2

mlogit y3 x1 x2

eststo m3

My question is how can I refer to the results of the three models in a single predictnl command?

I want to do a predictnl command as follows

predictnl gh = exp(alternative1)/(1+alternative1+alternative2) (from model 1) +
               exp(alternative1)/(1+alternative1+alternative2) (from model 2) +
               exp(alternative1)/(1+alternative1+alternative2) (from model 3) +

but do not know how to distinguish the three expressions on the right hand side in relation to the three models.

Regards,

Gerald
