WebChi-square Distribution with r degrees of freedom. Let X follow a gamma distribution with θ = 2 and α = r 2, where r is a positive integer. Then the probability density function of X is: f ( x) = 1 Γ ( r / 2) 2 r / 2 x r / 2 − 1 e − x / 2. for x > 0. We say that X follows a chi-square distribution with r degrees of freedom, denoted χ 2 ...
