DNAtools (version 0.1-8)

DNAtools-package: Tools for analysing forensic genetic DNA databases

Description

Computational efficient tools for comparing all pairs of profiles in a DNA database. The expectation and covariance of the summary statistic is implemented for fast computing. Routines for estimating proportions of close related individuals are available. The use of wildcards (also called F-designation) is implemented. Dedicated functions ease plotting the results.

Methods to evaluate the distribution of the number of alleles in DNA mixtures have been added. This includes methods to assess a drop-out probability, number of contributors and the distribution in it self.

Details

ll{ Package: DNAtools Type: Package Version: 0.1 Date: 2013-06-19 License: GPL (>= 2) } dbCompare: Compares make all n(n-1)/2 pairwise comparisons between profiles of a database with n DNA profiles. dbExpect: Computes the expected number of matching and partial matching loci for a given number of profiles in a database. dbVariance: Calculates the associated covariance matrix. pNoA: The distribution of the number of alleles for DNA mixtures. pContrib: Assess the posterior distribution for the number of contributors. estimatePD: Estimate the drop-out probability based on the number of alleles.
