Definition: Let $X$ be a random variable, let $c$ be a constant and let $n$ be a positive integer. Then, the $n$-th moment of $X$ about $c$ is defined as the expected value of the $n$-th power of $X$ minus $c$:

$\label{eq:mom} \mu_n(c) = \mathrm{E}[(X-c)^n] \; .$

The “$n$-th moment of $X$” may also refer to:
