Version 3.0-0 of bayesm is now on CRAN. All MCMC routines in this version have been recoded using rcpp-Armadillo. This results in speeds gains of between 2 and 30 times faster (hierarchical and density estimation routines are on the higher end of this range) than in bayesm version 2.2-5. The algorithm, rsurGibbs, has been improved for better speed as well as recoded. A Bayesian treatment of aggregate random coefficient models (with instruments) has been added, see rbayesBLP. peter rossi thanks to Neil Fultz, Keunwoo Kim, and Wayne Taylor for their help in the recoding.
