This category contains results about the chi-squared distribution.
Definitions specific to this category can be found in Definitions/Chi-Squared Distribution.
Let $r$ be a strictly positive integer.
Let $X_1, X_2, \ldots, X_r$ be $r$ pairwise independent continuous random variables each with a standard Gaussian distribution.
Let $X := \ds \sum_{i \mathop = 1}^r {X_i}^2$ be the sum of the squares of $X_1, X_2, \ldots, X_r$.
Then $X$ is said to have a chi-squared distribution with $r$ degrees of freedom.
This is written:
- $X \sim \chi_r^2$
where $\chi$ is the Greek letter $\chi$ (chi).
