Ramos and Gonzalez-Rodriguez introduce the concept of calibration in order to determine whether a system of evidence presentation is a reliable assessor of evidential weight. In this paper, we apply this calibration method to a dataset of mixed forensic DNA profiles generated using the QIAGEN Investigator® 24plex QS Kit and interpreted using the probabilistic genotyping software STRmix™.We describe the methodology for applying calibration to sets of forensic DNA profiles. We observe an approximate correspondence of the posterior probability, as assigned from the <i>LR</i> and the prior odds, with the observed rate of true donors for this dataset.
