Methods

aName :: MHG a -> String

aIteration :: MHG a -> Int

aIsInValidState :: MHG a -> Bool

aIterate :: ParallelizationMode -> MHG a -> IO (MHG a)

aAutoTune :: Int -> MHG a -> IO (MHG a)

aResetAcceptance :: MHG a -> MHG a

aSummarizeCycle :: MHG a -> ByteString

aOpenMonitors :: AnalysisName -> ExecutionMode -> MHG a -> IO (MHG a)

aExecuteMonitors :: Verbosity -> UTCTime -> Int -> MHG a -> IO (Maybe ByteString)

aStdMonitorHeader :: MHG a -> ByteString

aCloseMonitors :: MHG a -> IO (MHG a)

aSave :: AnalysisName -> MHG a -> IO ()

mhg :: Settings -> PriorFunction a -> LikelihoodFunction a -> Cycle a -> Monitor a -> InitialState a -> GenIO -> IO (MHG a)

Initialize an MHG algorithm.

NOTE: Computation in the IO Monad is necessary because the trace is mutable.

mhgSave :: ToJSON a => AnalysisName -> MHG a -> IO ()

Save an MHG algorithm.

mhgLoad :: FromJSON a => PriorFunction a -> LikelihoodFunction a -> Cycle a -> Monitor a -> AnalysisName -> IO (MHG a)

Load an MHG algorithm.

See mcmcContinue.

type MHGRatio = Log Double

MHG ratios are stored in log domain.

mhgAccept :: MHGRatio -> GenIO -> IO Bool

Accept or reject a proposal with given MHG ratio?
