I need your help. I want to use Bradley-Terry model as logistic regression (with intercept=0, x_ij=(1,-1)). I have only student version and the function genreg ist not avaible for me.
I want to get the same results like there: http://support.sas.com/kb/24/992.html
When I have used the same datatable like in SAS-example (with y=win/total), the logreg didn't work. I tried also another structure of data:But it was also not helpful.
I have no idea, how the structure of data shuld be.
