**Description**


In most nested execution contexts, the outer loop is operating
on the set of moments and level mappings returned by an inner loop UQ method.
Thus ``qoi_statistics`` is the default.

Sub-specifications include the type of ``final_moments`` ( ``none``, ``standard``,
or ``central``) and the sense of ``distribution`` functions ( ``cumulative`` or
``complementary``).
