 This repository contains code to generate a R package ("contamMix") that implements a mixture-model used to estimation contamination in ancient  mitochondrial DNA using MCMC.  The model is detailed in supplementary information 5 ("Likelihood-based method for contamination estimation") of the following paper, which remains the best citation if using this method in a publication:
