WebJun 11, 2024 · Binary Classification in R: Logistic Regression, Probit Regression and More. In this post we describe how to do binary classification in R, with a focus on logistic regression. Some of the material is based on Alan Agresti’s book [1] which is an excellent resource. For many problems, we care about the probability of a binary outcome taking ... WebLinear classification. Problem 3: We want to create a generative binary classification model for classifying non-negative one-dimensional data. This means, that the labels are binary (y ∈ { 0 , 1 }) and the samples are x ∈ [0, ∞). We assume uniform class probabilities.
