FBI2015freqs: FBI 2015 Population Data for the expanded CODIS core STR loci

Description

A data set containing allele frequencies for 23 autosomal STR loci from the FBI 2015 population data set. Frequencies are provided for are determined with both the GlobalFiler and Fusion kits in African Americans, Caucasians, Southeastern Hispanics, Southwestern Hispanics, Bahamians, Jamaicans, Trinidadians, Apaches, Navajos, Chamorros and Filipinos.

Usage

FBI2015freqs

Format

A named list of length 12.

Each element is itself a named list of 23 STR loci, with named numeric vectors of allele frequencies.

Details

Each population group is a named list of 23 elements, where each element corresponds to a specific STR locus (e.g., D3S1358, vWA, FGA, etc.). Each locus is represented as a named numeric vector:

• Names: allele values (as character strings, e.g., "12", "14.2")

• Values: allele frequencies for that population group

An attribute "N" is attached to each population list, specifying the sample size (number of alleles) for each locus.
