st: Re: constraint for mlogit

["Hannah Kewsberry" <hannah_kewsberry@hotmail.com>]

Hi Thomas,

Thanks for your prompt attentions to my question. I would like to constraint 
income (just one estimate) for all choices because I want to see by 
including income as an endogenous variable in the multinomial logit 
equation, what effect will it be on other coefficients for the different 
choices.

I have tried using command such as the following to constsraint my income:

constraint define 1 [transport]income=0
mlogit transport age distance status income, constraint (1)

The response given take income as 0 for the above command, and the rest 
worked perfectly. What I want now is how can I come up with a command that 
will constraint income like as if it is a constant, rather than 0.

This equation is slightly more complex than usual, and I hope to hear 
suggestions. Thanks.

Regards,

Hannah
