Web3.1 Introduction to Logistic Regression We start by introducing an example that will be used to illustrate the anal-ysis of binary data. We then discuss the stochastic structure of the data in terms of the Bernoulli and binomial distributions, and the systematic struc-ture in terms of the logit transformation. The result is a generalized linear WebRunning a logistic regression model.
