I have a question regarding quasi-complete separated data.
One example of quasi-complete separation is a dataset, where all x < 2 have y=1, all x > 2 have y=0 and some x=2 have y=0 and some x=2 have y=1.
I have a dataset with kind of the following situation: for all x < 2 y=0, for all x > 5 y=1. In the rage x=2 to x=5 y is sometimes zero and sometimes one.
Is this a case of quasi-complete separation as well?
Does is matter for logistic regression if the range of x=2 to x=5, where y varies, is small?
An example how my data look like:
