Web1 Neyman-Fisher Factorization Theorem Theorem 2. The statistic T is sufficient for θ if and only if functions g and h can be found such that f X(x θ) = h(x)g(θ,T(x)) (2) 1. The central idea in proving this theorem can be found in the case of discrete random variables. Proof. Because T is a function of x, In probability theory and statistics, the F-distribution or F-ratio, also known as Snedecor's F distribution or the Fisher–Snedecor distribution (after Ronald Fisher and George W. Snedecor) is a continuous probability distribution that arises frequently as the null distribution of a test statistic, most … See more The F-distribution with d1 and d2 degrees of freedom is the distribution of $${\displaystyle X={\frac {S_{1}/d_{1}}{S_{2}/d_{2}}}}$$ where $${\textstyle S_{1}}$$ and $${\textstyle S_{2}}$$ are … See more • If $${\displaystyle X\sim \chi _{d_{1}}^{2}}$$ and $${\displaystyle Y\sim \chi _{d_{2}}^{2}}$$ (Chi squared distribution) are independent, then • If See more • Beta prime distribution • Chi-square distribution • Chow test • Gamma distribution See more A random variate of the F-distribution with parameters $${\displaystyle d_{1}}$$ and $${\displaystyle d_{2}}$$ arises as the ratio of two appropriately scaled chi-squared variates: $${\displaystyle X={\frac {U_{1}/d_{1}}{U_{2}/d_{2}}}}$$ where See more • Table of critical values of the F-distribution • Earliest Uses of Some of the Words of Mathematics: entry on F-distribution contains a brief history See more
