Logistic Regression in R, Clearly Explained!!!!

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: https://github.com/StatQuest/logistic_regression_demo/blob/master/logistic_regression_demo.R For more details on what's going on, check out the following StatQuests: For a general overview of Logistic Regression: https://youtu.be/yIYKR4sgzI8 The odds and log(odds), clearly explained: https://youtu.be/ARfXDSkQf1Y The odds ratio and log(odds ratio), clearly explained: https://youtu.be/8nm0G-1uJzA Logistic Regression, Details Part 1, Coefficients: https://youtu.be/vN5cNN2-HWE Logistic Regression, Details Part 2, Fitting a line with Maximum Likelihood: https://youtu.be/BfKanl1aSG0 Logistic Regression Details Part 3, R-squared and its p-value: https://youtu.be/xxFYro8QuXA Saturated Models and Deviance Statistics, Clearly Explained: https://youtu.be/9T0wlKdew6I Deviance Residuals, Clearly Explained: https://youtu.be/JC56jS2gVUE For a complete index of all the StatQuest videos, check out: https://statquest.org/video-index/ If you'd like to support StatQuest, please consider...
