Dear all,
Hope you are fine.
I actually need to test whether my OLS regression is trustworthy or no using the residuals test (q-q plot).
what I understand is that the fitted model should look as follows: all points should be ( located) on the straight line. But when I use this method with binary dependent variable the q-q plot diagram comes out differently as attached above
my question is can we use the q-q plot with a binary DV ?
If yes , does the outcome of mine in the pic above is fine. that is, Is my logistic regression trustworthy ?
If no, Kindly guide me how to use it with a binary DV?
Overall, I need to check whether my logistic regression is trust worthy or not.
thank you in advance
