    Thanks a lot. So, if I understand well, I have to check for multicollinearity in all cases, except if all my explanatory variables are nominal / categorical, correct?

    Is it necessary to check for multicollinearity of explanatory variables in logistic regression?

    Checking for multicollinearity of independent variables is necessary in linear regression since multicollinearity increases the standard error, which in turn affects t-stats and p-values. But in logistic regression, p-values are based on Khi2, therefore multicollinearity has no effect on the...
