Hi,

I am running the MNP package in R. The model runs well. There are actually 4 choices and 4th is considered as base category. I got the result of all 19 covariates for all 3 model choices. What I want to do with the result is to eliminate all the covariates from one model choice except constant and to eliminate only one covariate from other model choice except constant and the third model choice remains with all the 19 covariates and constant (in other words, Exclusion restriction). I am working on a data to test for the existence of complementarity. For this I need the results as I mentioned above.

Model Choice:B1               Model Choice: B2                                           Model Choice:B3
Constant only                 Constant + 18 covariates                                  Constant + 19 covariates
Blue color shows the result what I want. 

Waiting for the good suggestions
