nflscrapR-models repository

This repository contains the following folders for code inside the R folder:

• cmsac_posts - code for posts on Carnegie Mellon Sports Analytics Club site.
• init_models - code for creating the same expected points (EP), field goal, and win probability (WP) models. that are used in the nflscrapR package
• legacy_model_code - old version of code for creating nflscrapR models.
• loso_cv_calibration - code for calculating the leave-one-season-out cross validation calibration results and generating the calibration plots in the nflWAR paper for the nflscrapR models. Includes code for an alternate form of the EP model using ordinal logistic regression, which yields dramatically worse calibration results.
• nflWAR_paper_figures_code - code for generating the figures related to the EP and WP models seen in the nflWAR paper.
