WebNov 27, 2024 · Logistic Regression: To classify the response, chd, we are simply trying to classify a binary response. We thus attempt to model the probability that our response belongs to one group, given the predictors X. We model the so called logit, this ensures that our estimates remain in the interval [0,1] as we are modelling a probability.
