1. Exploratory Data Analysis[1] 1.3. EDA Techniques[2] 1.3.6. Probability Distributions[3] 1.3.6.6. Gallery of Distributions[4] 1.3.6.6.5. F Distribution Probability Density Function [5] The F distribution is the ratio of two chi-square distributions with degrees of freedom ν1 and ν2, respectively, where each chi-square has first been divided by its degrees of freedom. The formula for the probability density function of the F distribution is ( f(x) = frac{Gamma(frac{ u_{1} + u_{2}} {2}) (frac{ u_{1}} { u_{2}}){frac{ u_{1}} {2}} x{frac{ u_{1}} {2} - 1 }} {Gamma(frac{ u_{1}} {2}) Gamma(frac{ u_{2}} {2}) (1 + frac{ u_{1}x} { u_{2}}){frac{ u_{1} + u_{2}} {2}} } ) where ν1 and ν2 are the shape parameters and Γ is the gamma function. The formula for the gamma function is ( Gamma(a) = int_{0}{infty} {t{a-1}e{-t}dt} ) In a testing context, the F distribution is treated as a "standardized distribution" (i.e., no location or scale parame...取得本站獨家住宿推薦 15%OFF 訂房優惠
