Petunjuk latihan

  • Fit a GAM to the mpg data, modeling city.mpg as a sum of smooth functions of weight, length, and price, and also include the categorical terms fuel, drive, and style.
  • Use the plot() function provided to visualize the model.

Latihan interaktif praktis

Cobalah latihan ini dengan menyelesaikan kode contoh berikut.

library(mgcv)

# Fit the model
mod_city2 <- gam(city.mpg ~ s(weight) + s(length) + s(price) ___, 
                 data = mpg, method = "REML")

# Plot the model
plot(mod_city2, all.terms = TRUE, pages = 1)
