Logistic Regression in R, Clearly Explained!!!!
Ideas Tags: Clearly, explained, Logistic, RegressionNo Comments »
This video describes how to do Logistic Regression in R, step-by-step. We start by importing a dataset and cleaning it up, then we perform logistic regression on a very simple model, followed by a fancy model. Lastly we draw a graph of the predicted probabilities that came from the Logistic Regression.
The code that I use in this video can be found on the StatQuest GitHub:
