title: Is the 2p rule always conservative?
abstract: The 2p rule is commonly used to interpret partial DNA profiles where dropout may have occurred. Recently this approach has been questioned in court. We investigate the performance of this rule, and give conditions under which it may be relied upon. Our analysis leads us to recommend an alternative approach. This may be used in all circumstances or reserved for those circumstances under which the 2p rule is not conservative.
