residual analysis

[noetsi]

I don't know how to use residuals in logistic regression to test for non-linearity because I have so much data (thousands of points).

This is an example of what I mean. There are indications of non-linearity in the box tidwel. But I don't see any in this. What are you looking for?

I have an interval predictor (that can not go below 0) and a bivariate dependent variable.

if you have any residual analysis left on after you are done, you should wipe it down with a clean microfiber cloth. good as new!
