subpavings::UniformSSMProposal Class Reference

The 'stay-split-merge' base chain proposal class, where probability of staying in same state $ \sigma $ is fixed, the probability of a split is $ \frac{1-\sigma}{2} $, the probability of a merge is $ \frac{1-\sigma}{2} $ and, given a split, the probabilities of each leaf being chosen are equal, and given a merge, the probabilities of each cherry being chosen are equal.
