Plotting multiple auto performance variables
In plotting GAMs, you sometimes want to look at just parts of a model, or all the terms in model. Here you'll practice selecting which terms to visualize.
This exercise is part of the course
Nonlinear Modeling with Generalized Additive Models (GAMs) in R
Exercise instructions
- Plot the provided model (
mod
) that uses thempg
data, using theselect
term to view only the partial effect ofprice
. - Make another plot, this time showing all terms on a single page, including the linear
comp.ratio
term.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
library(mgcv)
# Fit the model
mod <- gam(hw.mpg ~ s(weight) + s(rpm) + s(price) + comp.ratio,
data = mpg, method = "REML")
# Plot the price effect
___
# Plot all effects
___
