Hey everyone,

I am currently running a logistic regression with several independent variables.

As for the diagnostic requirements, I have to find out if there are no outliers beyond +/-3 (best case scenario +/-2), no multicollinearity and if there's linearity of logits (linear relationship between metric factor & logit function of the dependent variable).

While I have found out how to control for multicollinearity, I still don't know how to do outlier diagnostics and the linearity of logits assumption in the logistic regression with multiple independent variables.

Can somebody shed a light on these two issues?

Thank you.
