TL;DR: The interpretation of mixed DNA stains is explained in the context of likelihood ratios, and includes the "2p" modification suggested by the 1996 NRC report.
Abstract: The interpretation of mixed DNA stains is explained in the context of likelihood ratios. The probabilities for the mixed- stain profile are evaluated under alternative explanations that spec- ify the numbers of contributors and the profiles of any known contributors. Interpretations based simply on the frequencies with which random members of a population would not be excluded from a mixed-stain profile do not make use of all the information, and may overstate the strength of the evidence against included people. The effects of the numbers of contributors depends on whether all the alleles at a locus are present in the mixed stain. A general equation is given to allow likelihood ratios to be calculated, and includes the "2p" modification suggested by the 1996 NRC report. This modification is not always conservative. A computer program to perform calculations is available.

TL;DR: In this article, a divisive method for dealing with the grouping problem is proposed, which is compared with the agglomerative methods currently in use via Monte Carlo simulation, and the results show that the divisive method is more accurate than the traditional Monte Carlo method.
