In probability and statistics, the inverse-chi-squared distribution (or inverted-chi-square distribution ) is a continuous probability distribution of a positive-valued random variable. It is closely related to the chi-squared distribution. It arises in Bayesian inference, where it can be used as the prior and posterior … Ver mais • Scaled-inverse-chi-squared distribution • Inverse-Wishart distribution Ver mais • InvChisquare in geoR package for the R Language.

It is often applied to assess whether sample data are representative of the entire population. The chi-squared quality-of-fit test, in other words, is a kind of Pearson chi-squared test.
Web10 de mar. de 2024 · The scaled inverse chi-squared distribution is the distribution for x = 1/s 2, where s 2 is a sample mean of the squares of ν independent normal random variables that have mean 0 and inverse variance 1/σ 2 = τ 2.The distribution is therefore parametrised by the two quantities ν and τ 2, referred to as the number of chi-squared …
