Hello, 
I am currently dealing with a xtprobit regression.
I 
have experimented a problem with the coefficient of a dummy variable. IT
 has not the sign that I expect, that is logical and obvious.
Maybe 
there is a problem in my dataset, when I have put in the data, or is a 
specific - and curious - characteristic of my sample, but maybe is a 
"technical" problem.
Can you suggest me some commands or procedures to understand if the variable is bad-built or there are some technical problems?

Thanks
