Linear Regression: Multicollinearity, Polynomial & Interacting Features [2021-02-25]

We wrap up our linear regression topic by discussing multicollinearity and ways to extend linear regression with polynomial features and interacting features. We then do a very basic walkthrough of what a linear regression project might look like. Finally we end the recording before we go in to launching a regression Kaggle competition!

Also, sorry for the extra audio background of the twin babies; usually their mom could help but she was getting her COVID-19 vaccine! 😄
