You might assign ordinal scores as follows
3. first choice
2. second choice
1. first choice
0. not chosen
You can then use models appropriate to ordered categorical data.

I would like to analyze ranking data in which respondents select three

not possible to estimate a rologit model for this case. Is there a
procedure
available for analyzing my problem in Stata?
