LRage: Likelihood ratio for age variable

Description

Likelihood ratio for age variable

Usage

LRage(
  MPa = 40,
  MPr = 6,
  UHRr = 1,
  gam = 0.07,
  nsims = 1000,
  epa = 0.05,
  erRa = epa,
  H = 1,
  modelA = c("uniform", "custom")[1],
  LR = FALSE,
  seed = 1234
)

Value

A value of Likelihood ratio based on preliminary investigation data. In this case, Age.

Arguments

MPa

Missing person age

MPr

Missing person age range.

UHRr

Unidentified person range

gam

Simulation parameter for UHR ages.

nsims

number of simulations.

epa

epsilon age

erRa

error rate in the database.

H

hipothesis tested, H1: UHR is MP, H2: UHR is not MP.

modelA

reference database probabilities, uniform assumes equally probable ages. Custom needs a vector with ages frequencies.

LR

compute LR values

seed

For reproducible simulations
