- All Implemented Interfaces:
- HastingsCoupledProposal, TimeDependentProposal
- public class IndependentHastingsCoupledProposal
- extends java.lang.Object
- implements HastingsCoupledProposal, TimeDependentProposal
This class implements an Hastings-Coupled proposal that generates
states independently using a common GeneralProposal
. It simply
refers appropriate method calls to the encapsulated
GeneralProposal
.
