Hi All,

I'm trying to implement a quasi symmetry model for data on twin 
pairs.  A crosstabulation of twin 1 by twin 2 (assumed symmetrical) 
stratified by another variable.  There is a good paper on this by 
Phil (?) McCloud and Darroch in Biometrika (1995) which explains the 
method, but I've not done this before so am not clear how to code 
these models.

Any help would be greatly appreciated.
