classtable: Calculates several classification statistics from binary prediction and criterion (e.g.; truth) vectors

Description

Calculates several classification statistics from binary prediction and criterion (e.g.; truth) vectors

Usage

classtable(prediction.v = NULL, criterion.v, sens.w = 0.5, cost.v = NULL,
  correction = 0.25, cost.outcomes = list(hi = 0, fa = 1, mi = 1, cr = 0))

Arguments

prediction.v

logical. A logical vector of predictions

criterion.v

logical A logical vector of criterion (true) values

sens.w

numeric. Weight given to sensitivity, must range from 0 to 1.

cost.v

list. An optional list of additional costs to be added to each case.

correction

numeric. Correction added to all counts for calculating dprime

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.
