optim_xi_poisson_gd: Optimise xi Poisson Goal Difference

In neilcuz/panenkar: Panenkar

Description

Optimise xi parameter of time weighting for poisson model using the difference in goal difference as the evaluation metric

Usage

optim_xi_poisson_gd(
  xi,
  results_estimate_xi,
  match_rows,
  goal_difference_actual
)

Arguments

xi	the value of xi to use in the time weight
results_estimate_xi	results dataset to estimate xi off of
match_rows	rows in the results dataset to estimate xi from
goal_difference_actual	home_goals - away_goals, what really happened to compute mean square error of predicted on

Value

mean square error in actual and predicted goal difference
