Predicting NFL Team Performance with ELO Rating, Home-Field Advantage, and QB Rating

Appendix to report

Data cleaning

• Filtered out teams that are no longer active in the NFL

• Added new variables for winning teams

• Filtered years so that only years with all values are included. This is done by filtering for only seasons in 1950 or earlier

• Filtered dataset to only show NYG and NYJ games

• Replaced all NA values for the playoff column with “r”

• Removed columns total_rating and importance as these statistics were only recorded starting in 2021 and are not relevant to data analysis

• Split main dataset into smaller datasets for research question. This allowed us to select specific columns that are relevant to each question
