We can use the following code to load and view a summary of the dataset: #load dataset Step 1: Load the Dataįor this example, we’ll use the Default dataset from the ISLR package. This tutorial provides a step-by-step example of how to perform logistic regression in R.

We then use some probability threshold to classify the observation as either 1 or 0.įor example, we might say that observations with a probability greater than or equal to 0.5 will be classified as “1” and all other observations will be classified as “0.” Thus, when we fit a logistic regression model we can use the following equation to calculate the probability that a given observation takes on a value of 1: The formula on the right side of the equation predicts the log odds of the response variable taking on a value of 1. β j: The coefficient estimate for the j th predictor variable.Logistic regression uses a method known as maximum likelihood estimation to find an equation of the following form: Logistic regression is a method we can use to fit a regression model when the response variable is binary.
