Module Contents

.. py:class:: SingleMasked[Tepoch: jexplore.sampling.EpochMH, Tstate: jexplore.sampling.StateMH, Tsampling: jexplore.sampling.SamplingMH](mask = None)

   Bases: :py:obj:`jexplore.steps.mh.AllChains`\ [\ :py:obj:`Tepoch`\ , :py:obj:`Tstate`\ , :py:obj:`Tsampling`\ ]


   Full parallel all chains MH or modsel step.

   :param mask: mask of the subspace on which this step si defined.


   .. py:method:: sc_masked_proposal(key, p, ch)
      :abstractmethod:


      Single chain masked proposal. This is a prototype.

      :param key: PRNG key
      :param p: single chain point
      :param ch: chain index

      :return: the proposed chain point, the transition log probability.



   .. py:method:: proposal(key, state)

      All chain proposal. This is a prototype.

      :param key: PRNG key
      :param state: current state

      :return: the new PRNG key, the proposed state, the transition log probability.
