Probability Theory: Continuous Probability Distribution | by Ashish Arora | Medium
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. We write T ∼ t ( r). The p.d.f. of T is: f ( t) = Γ ( ( r + 1) / 2) π r Γ ( r / 2) ⋅ 1 ( 1 + t 2 / r) ( r + 1) / 2 for − ∞ < t < ∞. Eric Jang: A Beginner’s Guide to Variational Methods: Mean-Field Approximation
