This article examines aspects of the probabilistic genotyping tool called the forensic statistical tool which has been criticized as a function that is neither signaled by the software nor disclosed in publications.
The authors investigated the effect of this function by creating a near clone of the model and applying it to five- and six-allele loci for three-person mixtures created in the expected population proportions. The authors investigated the effect of this function by creating a near clone of the model and applying it to five- and six-allele loci for three-person mixtures created in the expected population proportions. On average, the dropping of a locus is conservative for six-peak loci and nonconservative for five-peak loci. For persons of interest (POIs) with rare alleles, the dropping is usually conservative. For POIs with common alleles, the dropping of the locus is often nonconservative. (Publisher abstract provided)
