Random real number moment
Formulation 1
Let $X \in \text{Random}(\mathbb{R})$ be a D3161: Random real number such that
(i) $p \in (0, \infty)$ is a D5407: Positive real number
(ii) \begin{equation} \mathbb{E} |X|^p < \infty \end{equation}
The moment of $X$ with respect to $p$ is the D993: Real number \begin{equation} \mathbb{E} X^p \end{equation}
