Jiayang GU

Tendency: Players in the league shot three more

30 teams in the league.

Pick and study top five scored players for each team

Collect 2015-2016 season and 2016-2017 season data

Totally: 30(teams)*5(players)*2(seasons)=300 Observations

Prediction: PTSit= GPit+FGit+FTit+Kit

Dependent Variable: PTS(total points gained by each player in a season)

Independent variables: GP(game played)

FG (field-goal %)

FT (Free throw %)

K (three-point shot %)

Other control variables: FTM/G (Free throw made/game)

FTA/G (Free throw attempt/game)
