Graphical Linearity Assessment for One- and Two-Predictor Logistic Regressions

Logistic regression is a flexible tool for modeling binary outcomes. A logistic regression describes the probability, \(P\), of 1/“yes”/“success” (versus 0/“no”/“failure”) as a linear combination of predictors:

\[\text{log}\left(\frac{P}{1-P}\right) = B_0 + B_1X_1 + B_2X_2 + ... + B_kX_k\]
