oneapi::mkl::stats::raw_moment#
Description#
Entry point to compute arrays of raw moments up to 4th order.
Mathematical Notation#
Vector of raw moments values:
\(R^k(X) = \left( R^k_1(X), \; \dots, R^k_p(X) \right), \; R^k_i(X) = \frac{1}W \sum_{j=1}^n \omega_j x_{ij}^k\)
Where:
\(W = \sum_{j=1}^n \omega_j, \; j = 1, \dots, p; k = 1, 2, 3, 4\)
