Computes rolling career value ratings for each player from per-match WPA and ERA values. Uses exponential time decay and Bayesian shrinkage toward a role-specific replacement-level prior.
Usage
calculate_epr(
format = c("t20", "odi", "test"),
player_game_data = NULL,
ref_date = NULL,
decay_batting = NULL,
decay_bowling = NULL,
prior_matches = EPR_PRIOR_MATCHES,
prior_rate = EPR_PRIOR_RATE
)Arguments
- format
Character. "t20", "odi", or "test".
- player_game_data
data.table from
load_player_game_data. If NULL, loads automatically.- ref_date
Date. Compute EPR as of this date (NULL = latest + 1 day).
- decay_batting
Numeric. Decay constant in days for batting component.
- decay_bowling
Numeric. Decay constant in days for bowling component.
- prior_matches
Numeric. Prior pseudo-matches for shrinkage.
- prior_rate
Numeric. Prior rate (typically 0 = replacement level).
