A Practical Tutorial on Checking Regression Assumptions

Statisticians advise that regression assumptions should be checked by plotting residuals to look for violations, rather than using tests of assumptions. This seminar will teach you how to interpret residual plots, and what to do when assumptions are not met. We will look at what good and bad residual plots look like, talk about what to look for, and test ourselves on examples to help you build an intuition.

The talk will be about 40 minutes long and following by discussion.
