Posterior rank summaries from player-strength draws

Convert posterior draws of player-level strength parameters into posterior summaries for player ranks. Ranks are computed draw by draw with rank 1 as the strongest player.

Usage

compute_expected_wins_rank_posterior(
  lambda_item,
  w_ij = NULL,
  player_names = NULL,
  burn_in = 0,
  thin = 1,
  ci = 0.95,
  ties.method = "average",
  rank_grid_by = 0.5
)

Arguments

lambda_item

Numeric matrix or list of posterior draws for player strengths, or a simple BT/PL or item-SBM btsbm_fit object.

w_ij

Optional wins matrix kept for API compatibility and ignored.

player_names

Optional names for the players.

burn_in

Burn-in as an integer iteration count or a fraction in [0, 1).

thin

Thinning interval.

ci

Posterior interval level.

ties.method

Passed to base::rank().

rank_grid_by

Spacing for the posterior rank probability grid.

Value

A list containing rank draws, a posterior rank-probability matrix, and summary statistics for each player.
