Chi-squared distribution
text:
In probability theory and statistics, the chi-squared distribution with k degrees of freedom is the distribution of a sum of the squares of k independent standard normal random variables. The chi-squared distribution χ k 2 is a special case of the gamma distribution and the univariate Wishart distribution. Specifically if X ∼ χ k 2 then X ∼ Gamma and X ∼ W 1. The scaled chi-squared distribution s 2 χ k 2 is a reparametrization of the gamma distribution and the univariate Wishart distribution. Sp
