**Description**


Allows the user to select between ``pick_and_freeze``
and ``binned`` for variance-based decomposition.

**Default Behavior**

Default method is ``pick_and_freeze``.




**Examples**



.. code-block::

    method,
      sampling
        sample_type lhs
        samples = 100
        variance_based_decomp
          vbd_sampling_method pick_and_freeze
