BAyesian Reference analysis in the Background Interference (BARBI)

A package for distinguishing true taxa from DNA contamination in molecular microbial studies. The BARBI package provides three important functions: alphaBetaNegControl, alphaBetaContInPlasma and samplingPosterior.

alphaBetaNegControl function

The alphaBetaNegControl function estimates the parameters of the distribution of the contamination intensity in negtiave control samples.

alphaBetaContInPlasma function

The alphaBetaContInPlasma function estimates the parameters of the distribution of the contamination intensity in specimen samples.

samplingPosterior fucntion

The samplingPosterior function samples from the posterior distribution of the true intensity.
