Glossary

Park Factor compares the rate of stats at home vs. the rate of stats on the road. A rate higher than 1.000 favors the hitter. Below 1.000 favors the pitcher. Teams with home games in multiple stadiums list aggregate Park Factors.

PF: ((homeRS + homeRA)/(homeG)) / ((roadRS + roadRA)/(roadG))
homeRS: Runs scored at home
homeRA: Runs allowed at home
homeG: Home games

roadRS: Runs scored on the road
roadRA: Runs allowed on the road
roadG: Road games
