StatQuest: Logistic Regression
Рет қаралды 2,168,822
Күн бұрынLogistic regression is a traditional statistics technique that is also very popular as a machine learning tool. In this StatQuest, I go over the main ideas so that you can understand what it is and how it is used.

Just want to say the quality of the video is top-notch. I'm currently pursuing MS in data science at a top-5 university in the US, but I did not find materials that explain logistic regression so clearly in such short space, and that managed to connect several related concepts together. Thank you for doing this!

Way too many materials pontificate. "Consider a perpendicular set of data that is in concordance with the average to a set variance within a dataset that has parametric properties" Translation: "Here are residuals on data normally distributed". It is actually quite shocking how many "advanced topics" when properly broken down and disseminated aren't nearly as difficult to learn.
