estimate_player_value_added: Calculate the 3 Types iPA and iPAA Values for Each Player

In ryurko/nflWAR: Computes WAR for Offensive Players in the NFL

Description

Calculate the 3 Types iPA and iPAA Values for Each Player

Usage

estimate_player_value_added(model_data_list, model_formula_list,
  return_models = 1)

Arguments

model_data_list	List of data frames: "pass_model_df" - Passing play-by-play data "rush_model_df" - Rushing play-by-play data "QB_table" - Table of QBs "RB_table" - Table of RBs "WR_table" - Table of WRs "TE_table" - Table of TEs
model_formula_list	List of the following formulas: "air_formula" - Formula for airEPA/airWPA model. "yac_forumla" - Formula for yacEPA/yacWPA model. "qb_rush_formula" - Formula for QB rushing/sacks model. "main_rush_formula" - Formula for non-QB rushing model.
return_models	Indicator for whether or not the models should be return in the list (default is yes, 1).

Value

Only return the original position tables from the input but modified so that the following columns are included:

• "air_iPA" - Individual player points/probability added in the air.

• "yac_iPA" - Individual player points/probability added after the catch.

• "rush_iPA" - Individual player points/probability added from rushing.

• "air_iPAA" - Individual player points/probability above average in the air.

• "yac_iPAA" - Individual player points/probability above average after the catch.

• "rush_iPAA" - Individual player points/probability above average from rushing.

as well as the resulting models:

• "air_model" - Model fit for air component

• "yac_model" - Model fit for yac component

• "qb_rush_model" - Model fit for QB rushing/sacks

• "main_rush_model" - Model for for all non-QB rushing attempts

Examples

# Estimate the player effects and get the iPA and iPAA values:
model_data_list <- model_data_list %>%
  estimate_player_value_added(model_formula_list, "none")
