This category contains results about **moments** in the context of **Probability Theory**.

Definitions specific to this category can be found in Definitions/Moments (Probability Theory).

Let $X$ be a random variable on some probability space.

Let $a$ be a real number.

Then the **$n$th moment of $X$ about $a$**, usually denoted $\map {\mu_n} a$, is defined as:

- $\map {\mu_n} a = \expect {\paren {X - a}^n}$

where $\expect X$ denotes the expectation of $X$.
