Hello,
I did not include interactions. Would it be better to include them? The
syntax is correct, I think. The predictors correlate with each other. Could
this be the problem? I have read that it is only a problem, if the
correlation is about .80?
In the models, including only one or two predictors (each significant), the
Hosmer-Lemshow Test is also significant, indicating a bad model fit? I dont
know, what to do now. Would a stepwise logistic regression be better? Should
I exclude predictors?
Hope, you can help me!
Best wishes,
JR
