WebNov 11, 2024 · Math and Logic. 1. Introduction. In this tutorial, we’re going to learn about the cost function in logistic regression, and how we can utilize gradient descent to compute the minimum cost. 2. Logistic Regression. We use logistic regression to solve classification problems where the outcome is a discrete variable. WebHowever, a nonlinear equation can take many different forms. In fact, because there are an infinite number of possibilities, you must specify the expectation function Minitab uses to …
