Summary

This is the author speaking here. What a great chapter! Yeah, I know I should not say that since I am the author of the book, nevertheless, I think the one you just completed was a relevant step towards your discovery of R for data mining. You are now able to:

Fit a linear model in R, both having a single explanatory variable and multiple explanatory variables (univariate and multivariate) through the lm() function and assess its estimates through the summary() function
Evaluate whether the linear regression model assumptions are met, through the durbinWatsonTest() and NCVtest() functions
Perform principal component regression on your data through the pcr() function
Perform stepwise regression through the stepAIC() function and evaluate its output
Compare and interpret the output and performance of different regression models and evaluate whether your model is a reasonable way to describe the observed phenomenon

It's now time to take a closer look at what a model performance, introducing...
