st: data management for nlogit

[Raja Chakir <raja.chakir@grignon.inra.fr>]

Dear List,

I have a data set that I would like to analyze with a nested logit (nlogit)
model.

The data set looks like:

id resto
1 A
2 A
3 B


I want the get the data that looks like:

id resto choice
1  A         1
1  B         0
2  A         1
2  B         0
3  A         0
3  B         1

Thank you very much for any help.

Sincerely,

Raja
