Decision Threshold: a function for computing likelihood ratio decision threshold.

Description

Decision Threshold: a function for computing likelihood ratio decision threshold.

Usage

DeT(datasim, weight)

Arguments

datasim	Input dataframe containing expected LRs for related and unrelated POIs. It should be the output from makeLRsims function.
weight	The differential weight between false positives and false negatives. A value of 10 is suggested.

Value

A value of Likelihood ratio suggested as threshold based on false positive-false negative trade-off.

Examples

library(forrel)
x = linearPed(2)
x = setMarkers(x, locusAttributes = NorwegianFrequencies[1:5])
x = profileSim(x, N = 1, ids = 2)
datasim = simLRgen(x, missing = 5, 10, 123)
DeT(datasim, 10)
