hoist :: (forall x. m x -> m x) -> Traced m a -> Traced m a Source #

marginal :: Monad m => Traced m a -> m a Source #

Discard the trace and supporting infrastructure.

freeze :: Monad m => Traced m a -> Traced m a Source #

Freeze all traced random choices to their current values and stop tracing them.

mhStep :: MonadDistribution m => Traced m a -> Traced m a Source #

A single step of the Trace Metropolis-Hastings algorithm.

mh :: MonadDistribution m => Int -> Traced m a -> m [a] Source #

Full run of the Trace Metropolis-Hastings algorithm with a specified number of steps.
