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 $${\displaystyle {\frac {X/d_{1}}{Y/d_{2}}}\sim \mathrm {F} (d_{1},d_{2})}$$ 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 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: See more • Beta prime distribution • Chi-square distribution • Chow test • Gamma distribution See more Webt検定は、t値と呼ばれる検定料を算出して、それをt分布表と見比べてp値を出します。 フィッシャーの正確確率検定は、分布表と見比べることをしない. 一方、フィッシャーの正確確率検定はどうしているか。 その名の … duties of a cfo non profit
