| dc.description.abstract | Using a simplified model, we examine the effect of varying the number of contributors in the prosecution and alternate propositions for a number of simulated examples.
We compare the Slooten and Caliebe [1] solution, with several existing practices. Our own experience is that most laboratories, and ourselves, assign the number of contributors, N = n, by allele count and a manual examination of peak heights. The LRn for one or a very few values is calculated and typically one of these is presented, usually the most conservative. This gives an acceptable approximation.
Reassessing the number of contributors if LR = 0 and adding one to N under both Hp and Ha to “fit” the POI may lead to a substantial overstatement of the LR.
A more reasonable option is to allow optimisation of the assignment under Hp and Ha separately.
We show that an additional contributor explained the single locus profile better when
PHR≥0.51.
This is pleasingly in line with current interpretation approaches.
Collectively these trials, and the solid theoretical development, suggest that the Slooten and Caliebe approach preforms well. | en_US |
