test.bracket: Test a bracket

In mRchmadness: Numerical Tools for Filling Out an NCAA Basketball Tournament Bracket

Description

Test a bracket

Usage

test.bracket(bracket.empty, bracket.picks, prob.matrix = NULL,
  prob.source = c("pop", "Pom", "538"), pool.source = c("pop", "Pom",
  "538"), league = c("men", "women"), year = 2017, pool.size = 30,
  num.sims = 1000, bonus.round = c(1, 2, 4, 8, 16, 32),
  bonus.seed = rep(0, 16), bonus.combine = c("add", "multiply"))

Arguments

bracket.empty	a length-64 character vector giving the field of 64 teams in the tournament, in order of initial overall seeding
bracket.picks	an length-63 character vector encoding your picks (this is the bracket to be evaluated)
prob.matrix	a matrix of probabilities, with rows and columns corresponding to teams, matching the output of bradley.terry(). This probabilities are used to simulate outcomes on which to evaluate bracket.picks. If NULL, prob.source is used.
prob.source	source from which to use round probabilities to simulate outcomes — "pop": ESPN's population of picks (default), "Pom": Ken Pomeroy's predictions (kenpom.com), or "538": predictions form fivethirtyeight.com. Ignored if prob.matrix is specified.
pool.source	source from which to use round probabilities to simulate entries of opponents in pool. Same options as prob.source.
league	which league: "men" (default) or "women", for pool.source.
year	year of tournament, used for prob.source. Ignored if prob.matrix is specified.
pool.size	number of brackets in your pool (excluding yours), matters only if criterion == "win" (default is 30)
num.sims	number of simulations over which to evaluate the candidate brackets (default is 1000)
bonus.round	a length-6 vector giving the number of points awarded in your pool's scoring rules for correct picks in each round (default is 2^round)
bonus.seed	a length-16 vector giving the bonus awarded for correctly picking winner based on winner's seed (default is zero)
bonus.combine	how to combine the round bonus with the seed bonus to get the number of points awarded for each correct pick: "add" (default) or multiply

Examples

prob.matrix = bradley.terry(games = games.men.2017)
my.bracket = find.bracket(bracket.empty = bracket.men.2017,
  prob.matrix = prob.matrix, pool.source = "pop", league = "men",
  year = 2017)
result = test.bracket(bracket.empty = bracket.men.2017,
  bracket.picks = my.bracket, prob.matrix = prob.matrix,
  pool.source = "pop", league = "men", year = 2017)
