  • randomly divide a data set into a training set and a test set
  • calculate the test MSE (mean squared error)
  • calculate quickly the MSE for a number of models
  • visualize the variability of the MSE with ggplot
  • row-slice data frames
  • use R’s predict function
  • write for loops in R
  • write functions of two variables in R
  • combine functions and for loops
  • add titles and labels to plots in ggplot

WHY Should You Take This Course?

  • This course is for those looking to improve their R programming skills.
  • This course is for those with the background equivalent to what one would have after viewing my first two Udemy courses in linear and polynomial regression.
