ABSTRACT
It is usual to attach a numerical weight to a match between DNA obtained from a crime sample and DNA taken from a sample given by a suspect. In Chapter 2, we discussed the possibilities of using a frequency, an exclusion probability, or a likelihood ratio for this purpose. None of these methods
rather, an estimate is given and not an exact answer leads to the following question: “Should this numerical estimate be a ‘best’ estimate or should some consideration be given to the uncertainty in this estimate?” This is a matter where opinions in the forensic community differ.
