  3. Nonlinear Modeling with Generalized Additive Models (GAMs) in R

Exercise

Plotting the motorcycle crash model and data

For our first plotting exercise, we'll add partial residuals to the partial effect plot of a GAM so as to compare the model to the data.

Instructions

100 XP
  • Plot the model (mod) that uses mcycle data. Add partial residuals to the plot.
  • Make a second plot, making partial residuals more visible by changing the shape using the pch argument, and size of the residuals using the cex argument. Set both the pch and cex arguments to 1.
