aesara.tensor.random.wald = <aesara.tensor.random.basic.WaldRV object>[source]#

A Wald (or inverse Gaussian) continuous random variable.

The probability density function for wald in terms of its mean parameter $\mu$ and shape parameter $\lambda$ is:

$f(x; \mu, \lambda) = \sqrt{\frac{\lambda}{2 \pi x^3}} \exp\left(-\frac{\lambda (x-\mu)^2}{2 \mu^2 x}\right)$

for $x > 0$ , where $\mu > 0$ and $\lambda > 0$ .
