Detailed Description

Rising-factorial moments from raw moments, via the cycle numbers.

Templated port of matlab/src/api/moment/moment_upfactorial_from_raw.m. Every operation is integer or rational, so the exact instantiation returns the transform with no rounding at all. That matters more here than almost anywhere else in the API: the alternating binomial sums of the moment conversions cancel catastrophically in double arithmetic once the order grows.
