pyhs3.distributions.GaussianDist

class pyhs3.distributions.GaussianDist(*, name, mean, sigma, x)

Gaussian (normal) probability distribution.

Implements the standard Gaussian probability density function:

\[f(x; \mu, \sigma) = \frac{1}{\sigma\sqrt{2\pi}} \exp\left(-\frac{(x-\mu)^2}{2\sigma^2}\right)\]

Parameters:

• mean (str) – Parameter name for the mean (μ).

• sigma (str) – Parameter name for the standard deviation (sigma).

• x (str) – Input variable name.

• name (str)

__init__(*, name, mean, sigma, x)
