AdaptiveMultiMRW

This class implements an Adaptive Multi-site Metropolis random walk
algorithm.

MCMC

node

Implements a non-parametric source attribution model to attribute
cases of disease to sources in Bayesian framework with source and type effects.
Type effects are clustered using a Dirichlet Process. Multiple times and
locations are supported.
