I have a question regarding multicollinearity. One of the assumptions of a logistic regression is the absence of multicollinearity. My problem is that I dont know the proper way to test this.

I have different sorts of variables, which I want to check for multicollinearity on each other.

The variables consists of dummy's (0 or 1), likert-scale (5-points), ratio (like 0,2 etc) and absolute values (1.....99). So I want to check for multicollinearity for e.g. the dumy with the likert-scales etc.

Could anyone tell me what test or tests I should perform?

Thanks in advance.
