The chi-square distribution of statisticsAuthor Bai NingsuAugust 9, 2015 22:33:00 absrtact: This paper summarizes the study of the chi-square distribution of statistics. This article first describes what is the chi-square distribution and

Defined:If our random variable is a standard normal distribution (see the Gaussian distribution of previous blogs), then the squared and subordinate distributions of multiple random variables are chi-squared distributions.X=y12+y22+?+yn2Among them,

There are many statistical distributions, which are basically described in R. Due to their limited capabilities, we have selected a few common, more important, and simple descriptions of each distribution definition, formula, and presentation in
