threshold_factor_grid: Performs a grid search over factor and returns accuracy statistics for a given factor cue

Description

Performs a grid search over factor and returns accuracy statistics for a given factor cue

Usage

threshold_factor_grid(thresholds = NULL, cue.v = NULL, criterion.v = NULL,
  directions = "=", sens.w = 0.5, cost.outcomes = list(hi = 0, fa = 1, mi
  = 1, cr = 0), cost.each = 0, goal.threshold = "bacc")

Arguments

thresholds

numeric. A vector of factor thresholds to consider

cue.v

numeric. Feature values

criterion.v

logical. Criterion values

directions

character. Character vector of threshold directions to consider.

sens.w

numeric.

cost.outcomes

list. A list of length 4 with names 'hi', 'fa', 'mi', and 'cr' specifying the costs of a hit, false alarm, miss, and correct rejection rspectively. E.g.; cost.outcomes = listc("hi" = 0, "fa" = 10, "mi" = 20, "cr" = 0) means that a false alarm and miss cost 10 and 20 respectively while correct decisions have no cost.

cost.each

numeric.

goal.threshold

character.
