1Blurb::  Use the Delayed Rejection MCMC algorithm
2
3Description::
4This keyword specifies the use of the Delayed Rejection algorithm in
5which there can be a delay in rejecting samples from the chain.  That
6is, the "DR" part of DRAM is used but the "AM" part is not, rather a
7regular Metropolis-Hastings algorithm is used.
8
9<b> Default Behavior </b>
10
11Five MCMC algorithm variants are supported: \c dram, \c
12delayed_rejection, \c adaptive_metropolis, \c metropolis_hastings, and
13\c multilevel.  The default is \c dram.
14
15<b> Usage Tips </b>
16
17If the user knows something about the proposal covariance or the
18proposal covariance is informed through derivative information, using
19\c delayed_rejection is preferred over \c dram: the proposal covariance is
20already being informed by derivative information and the adaptive
21metropolis is not necessary.
