[Limdep Nlogit List] Variable reduction methods in probit models

[Eleimon Gonis]

Dear All,
 
Apart from factor analysis (and other related methods), is there any other quick and practical way of reducing the number of variables included in a probit model, either binary or ordered?
 
Apologies for the naive, for some, question.
 
Kind regards,
Eleimon
