# Load libraries library(caret) library(mlbench) library(earth) library(kernlab) library(nnet) library(AppliedPredictiveModeling) Exercise 7.2 Friedman (1991) introduced several benchmark data sets create by simulation. One of these simulations used the following nonlinear equation to create data: \[y = 10\sin(\pi x_1x_2) + 20(x_3 - 0.5)^2 + 10x_4...
