RE: [R] What is the most useful way to detect nonlinearity in logisticregression?

Dear Patrick, Component+residual plots can be defined for generalized linear models (including logistic regression) as for linear models, but they may require smoothing for interpretation. See, e.g., the cr.plots() functions in the car package, which works with glm objects. I hope this helps,
