docs/tutorial:stats:continuous_rice

There is one shape parameter $b \geq 0$ (the "distance from the origin") and the support is $x \geq 0$ .

were $I_{0} (y)$ is the modified Bessel function of the first kind of order 0.

μ_{n}^{'} = 2^{n} Γ (1 + \frac{n}{2})_{1} F_{1} (- \frac{n}{2}; 1; - \frac{b ^{2}}{2})

Implementation: scipy.stats.rice
