Abstract: There is a variety of methods for assessing sampling uncertainty in likelihood ratio calculations in DNA casework. Sampling uncertainty arises because all DNA statistical methods rely on a database of collected profiles. Such databases can be regarded as a sample from the population of interest. The act of taking a sample incurs sampling uncertainty. In some circumstances it may be desirable to provide some estimate of this uncertainty. The authors have addressed this topic in two previous publications. In this paper the authors reconsider the performance of the methods using 15 locus Identifiler™ profiles, rather than the 6 locus data used in a previous study. The authors also examine the differences in performance observed when using a uniform prior versus a 1/k prior in the Bayesian highest posterior density (HPD) method of Curran et al.
