MixBUGS
by eric.ward, last updated 9/24/08, sharing set to public
This project includes the WinBUGS files illustrating how to include model selection in MCMC. Variances are modeled as a mixture of source/fractionation and additional residual variance. We include to variations on the MixBUGS model, 1 without residual variance, and 1 modeling variance as a mixture (to calculate posterior probabilities). We also include the Rscript illustrating that the SIAR package likely contains a bug (even when data are generated from a 0.70.20.1 mixture, estimated contributions are nearly equal).
