Feedback

• Generally very positive feedback about TAs!

• Enjoy interactive lectures, want more time on AEs / live coding

• Rubric for assessments / grading

• Challenging topic list

Linear regression with a multiple predictors

Goals

• Recap modeling with a single predictor

• Fit and interpret models with multiple predictors

• Distinguish between additive and interaction models

Application exercise: ae-12-modeling-penguins-multi

• Go back to your project called ae.
• If there are any uncommitted files, commit them, and push.
• Work on ae-12-modeling-penguins-multi.qmd.
