Hi,

I was wondering if someone could help with defining multiple constraint using clogit. I have Stata version 14 & 15. The following works:

constraint 1 logprice = 1.132817
clogit target logprice norm_probs, group(raceid) constraint(1)

However, what I will like to do is define a constraint for the coefficient of logprice & norm_probs.

What I have done so far is:

. constraint 1 logprice = 1.132817

. constraint 2 norm_probs = 1.425557

clogit target logprice norm_probs, group(raceid) constraints(1 2)

I kept getting the following err0r message :'
redundant or inconsistent constraints
r(412);'

Any help will be highly appreciated!

Thanks,
Larry
