Hi.

Do I have to check linearity assumption of logistic regression (Log odds of outcome with continuous variable)

using graph of predicted logodds (by logistic regression) and continuous variable

Or

using graph with real logodds and continuous variable ?

I think the latter is right.

In univariate setting, the first one should be always perfect linear. Is it right?

Best.
