[Limdep Nlogit List] Comparing coefficients

[Harold Mayaba]

 Dear Professor Greene,
In line with the reply from Zein, the results are from three treatments analyzed separately.  I would like to establish if there is a statistically significant difference between the coefficients from three different treatments.  The method I found compares coefficients from each treatment as a group not individual coefficients. For example,  I have 'access to outdoor' attribute in each treatment.  I would like to compare the coefficients of this attribute i got from each treatment.  I hope this helps.
Regards 
Harold

 Dear Professor Greene and other nlogit user,
How can I compare two or three coefficients from different treatments to establish if there is a significant difference? I have seen literature where coefficients of different treatments are compared but not coefficients of the same attribute in different treatments.

Thanks
Harold
