Modelling mixing proportion variability across loci and uncertain peaks in a PGS

Research output: Contribution to conferencePoster

Abstract

LiRa is a probabilistic genotyping software (PGS) used to calculate the evidential strength of an autosomal DNA profile with respect to its origin, based on the peak heights taken from an electropherogram (EPG). The value produced by LiRa is a likelihood ratio, which is the likelihood under the prosecution hypothesis divided by the likelihood under the defence hypothesis. The current version includes a number of changes from the previous version. The two main differences are a new likelihood function for uncertain peaks and an allowance for the mixing proportions to vary between loci.
