[R] reduced set of alternatives in package mlogit

[Bert Gunter]

code? example data?  We can only guess based on your vague post.

"PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code."

Moreover, this sounds like a statistical question, not a question
about R programming, and so might be more appropriate for a
statistical list like stats.stackexchange.com  .

Cheers,
Bert
