**Description**


In this case, the expansion order $p$ cannot be inferred from the
numerical integration specification and it is necessary to provide an
``expansion_order`` to specify $p$ for a total-order expansion.

A corresponding sequence specification is documented at, e.g.,
:dakkw:`method-multifidelity_polynomial_chaos-expansion_order_sequence-expansion_samples_sequence` and
:dakkw:`method-multilevel_polynomial_chaos-expansion_order_sequence-expansion_samples_sequence`
