lesson 4 of 5 · regression metrics and residuals
step 2 of 7 in this lesson
A delivery-time model reports MAE = 4 minutes, RMSE = 19 minutes. What is that gap telling you?
1
Nothing — RMSE is always bigger than MAE
2
The error budget is concentrated in a few disasters — most predictions are fine, some are terrible
3
The model systematically under-predicts
4
The metrics are in different units
