Then, in future posts to be released throughout the tournament season over the next few weeks, I will be able to use the rating systems described here to answer some interesting questions about tournament teams in the past and what is happening in For this, we will need the following R packages, and a small dataset outlining an example season. The RPI is one of the most widely known and widely criticized rating systems used in College Basketball.
The main criticisms of the RPI is that it fails to take into account margin of victory and it places too much weight on facing strong opponents to the point where it clearly rewards teams for losing badly to many strong opponents and penalizes teams for playing well against weaker ones.
Though calculating the RPI seems simple on the surface, there are two additional caveats that make it a bit more challenging and a great example for functional programming. An additional weighting factor 1. If you are still confused, I highly recommend checking out the example here , which walks you through the calculation step-by-step. At any rate, once I get the WP for each opponent, I simply return the mean.
