population_assignment_module_spec.RdThe descriptor owns the complete population-assignment registry contract: a frequency-based self-assignment test (Paetkau et al. 1995, 2004) that scores each sample's leave-one-out genotype likelihood (Rannala and Mountain 1997) against every population's allele frequencies and flags samples that assign to a population other than their recorded metadata label – candidate migrants or metadata errors.
