Web26.4 - Student's t Distribution. We have just one more topic to tackle in this lesson, namely, Student's t distribution. Let's just jump right in and define it! Definition. If Z ∼ N ( 0, 1) and U ∼ χ 2 ( r) are independent, then the random variable: T = Z U / r. follows a t -distribution with r degrees of freedom. 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 ...
