st: interpret results from conditional logit model

["Wei Tan" <tanwei@hotmail.com>]

Hi,

I am sorry that my email account block the stata list last time. therefore I 
did not receive any reply from your list.

I am trying to use clogit to estimate McFadden's choice model. My question 
is how to interpret the results from Stata.

I will illustrate with the example in STATA Reference.

data:

id  car           choice         dealer sex

1  american     0              18      male
1  Japan         0               8       male
1  Europe       1               5       male
2  American    1               17      female
2  Japen         0               6        female
2  Europe       0                2       female


if I use the following command:

gen Japan=(car==2)
gen europe=(car==3
gen sexJap= sex*japen
gen sexeuro=sex*europe
clogit choice japan erupe sexjap sexeur dealer,group(id)

I have two questions:

1. How should I interprete the estimated coefficient and odds ratio for 
japan and dealer

2. if I want to restrict sex to have the same effect for Japan and Europe 
car. how should I do?

thanks
