.. py:function:: compute_weights(samples, nlive)

   
   Returns the log-evidence and log-weights for the log-likelihood samples
   assumed to the result of nested sampling with nlive live points


   :Parameters:

       **samples** : array_like
           Log-likelihood samples.

       **nlive** : int
           Number of live points used in nested sampling.

   :Returns:

       float
           The computed log-evidence.

       array_like
           Array of computed weights (already normalised by the log-evidence).

.. py:function:: draw_posterior_samples(nested_samples, nlive)

   
   Draw posterior samples given the nested samples and number of live points.


   :Parameters:

       **nested_samples** : structured array
           Array of nested samples.

       **nlive** : int
           Number of live points used during nested sampling.

   :Returns:

       array_like
           Samples from the posterior distribution.
