Hi all:
 
I'm trying use polychoric command to get correlation between categorical variables. There are about 2000 observations. 
Gender: male=1 female=2   and stress: yes=1 and no=0
 
I'm getting this "conformability error".
 
polychoric  gender Stress
conformability error
r(503);
 
Why am I getting this error?  I'm using STATA 7.
Please advise me. Thanks
Vinod
