Exercise

Setting complexity of the motorcycle model

The number of basis functions in a smooth has a great impact on the shapes a model can take. Here, you'll practice modifying the number of basis functions in a model and examining the results.

Instructions

100 XP

Fit a GAM with 3 basis functions to the mcycle data, with accel as a smooth function of times.
Fit the same GAM again, but this time with 20 basis functions.
Use the provided plot() functions to visualize both models.
