Hi,

 

after calculating an ordered logit regression I wanted to delete variables by using "stepwise regression", but it is not working. "data error" (Datenfehler!) occurs.

I already had a look for the collinearity and deleted some variables (collinearity around 3) on my own and tried stepwise regression again, but still "data error".

Is there a solution for my problem?

 

regards and many thanks
