BCE-package {BCE}

The Bayesian Compositional Estimator Package

Description

Functions that estimate sample (taxonomic) composition from biomarker data

bce1 estimates probability distributions of a sample composition based on an input ratio matrix, A, containing biomarker ratios in (field) samples, and an input data matrix, B, containing the biomarker ratios for several taxonomic groups

tlsce estimates the total least squares solution

This version differs from the previous version <2 in that a different MCMC method is used that shows better convergence properties and has a more sound underlying statistical model.
