Chi Square Distribution Formula. Gamma function Γis a generalization of the. The following theorem clarifies the relationship. If we have X as a gaussian random variable and we take the relation YX2 then Y has a chi-square distribution with one degree of freedom 21. The distribution of the chi-square statistic is called the chi-square distribution.
Generally there are two types of variables in statistics such as numerical variables and non-numerical variables. Chi 2 sum fracO-E2E Where O. 6 Expected number is. The Chi-Square is denoted bychi 2 and the formula is. The chi-square distribution is equivalent to the gamma distribution where α k2 and β 2. I was able to prove that the mean of a central chi-squared distribution is its degree n by using the formula.
