Bayesian Barcoding Inference
Definition
A method for assigning a DNA barcode sequence to a species that uses prior probabilities (the known composition of species in a trade network) and a likelihood function (how well the sequence fits reference data for each candidate species) to produce a posterior probability of species identity.
