WebMar 24, 2024 · The Fisher–Snedecor Distribution: A Simple and Accurate Composite Fading Model Abstract: We consider the use of the Fisher-Snedecor F distribution, which is defined as the ratio of two chi-squared variates, to model composite fading channels. WebCHISQ.INV：计算左尾卡方分布的反函数。 CHITEST：返回对 2 个数据范围进行的皮尔森卡方检验相关的概率。这用于判断观察到的类别数据来自预期分布的可能性。 F.INV：计算左尾 F 概率分布的反函数。此分布也称为 Fisher-Snedecor 分布或 Snedecor F 分布。

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 http://www.vue5.com/statistics/f_distribution.html chinese food chemainus bc
