Multiple Regression And Diagnostics

Add predictors while keeping interpretation honest.

Units

1. Unit 09.00: Every slope is now conditional
2. Unit 09.01: Levels minus one, all relative to the reference
3. Unit 09.02: Same fit, different comparisons
4. Unit 09.03: Only as good as the variables you measured
5. Unit 09.04: The interaction term is a difference of slopes
6. Unit 09.05: Look for pattern, not for size
7. Unit 09.06: One row can reverse the conclusion
8. Unit 09.07: Prediction survives; interpretation does not
9. Unit 09.08: R-squared always rises
