I'd bin the idea of using stepwise regression, if I were you. It's an entirely pointless and atheoretical way of fitting a statistical model. As a primer, look up what Frank Harrell has to say about it.

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
