FisherF

The ratio of two chi-squared distributions with degrees of freedom m (with default value 1.0) and n (with default value 1.0).

The probability density is given by,

$$f(x | m, n) = \frac{\[Gamma](../gamma/index.md)\left(\tfrac{m+n}{2}\right)}{\[Gamma](../gamma/index.md)\left(\tfrac{m}{2}\right)\[Gamma](../gamma/index.md)\left(\tfrac{n}{2}\right)} \left(\frac{m}{n}\right)^{\tfrac{m}{2}} x^{\tfrac{m}{2} - 1} \left(1 + \tfrac{mx}{n}\right)^{-\tfrac{m+n}{2}}.$$
