Notes

The probability density function for gausshyper is:

f (x, a, b, c, z) = C x^{a - 1} (1 - x)^{b - 1} (1 + z x)^{- c}

for $0 \leq x \leq 1$ , $a, b > 0$ , $c$ a real number, $z > - 1$ , and $C = \frac{1}{B ( a , b ) F [ 2 , 1 ] ( c , a ; a + b ; - z )}$ . $F [2, 1]$ is the Gauss hypergeometric function scipy.special.hyp2f1.

gausshyper takes $a$ , $b$ , $c$ and $z$ as shape parameters.
