What are Assumptions of Linear Regression? Easy Explanation for Data Science Interviews

In this video, we’ll go over the four assumptions of linear regression. Interviewers frequently ask questions about linear regression, so we’ll dive into both the assumptions themselves, as well as how to diagnose violations of the assumptions. I’ll also offer insight into which assumptions are critical versus which are less important.
