Webfor x > 0 and parameters d f 1, d f 2 > 0 . f takes dfn and dfd as shape parameters. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters. Specifically, f.pdf (x, dfn, dfd, loc, scale) is identically equivalent to f.pdf (y, dfn, dfd) / scale with y = (x ... WebThe random variate of the F distribution (also known as the Fisher distribution) is a continuous probability distribution that arises in ANOVA tests, and is the ratio of two chi-square variates. Note New code should use the f method of a Generator instance instead; please see the Quick Start. Parameters: dfnumfloat or array_like of floats
