%description
Provides functionality to perform a likelihood-free method for estimating
the parameters of complex models that results in a simulated sample from
the posterior distribution of model parameters given targets. The method
begins with a accept/reject approximate bayes computation (ABC) step
applied to a sample of points from the prior distribution of model
parameters. Accepted points result in model predictions that are within
the initially specified tolerance intervals around the target points. The
sample is iteratively updated by drawing additional points from a mixture
of multivariate normal distributions, accepting points within tolerance
intervals. As the algorithm proceeds, the acceptance intervals are
narrowed. The algorithm returns a set of points and sampling weights that
account for the adaptive sampling scheme. For more details see Rutter,
Ozik, DeYoreo, and Collier (2018) <arXiv:1804.02090>.
