stats_dens_gamma — Probability density function of the gamma distribution

Descrizione

function stats_dens_gamma(float $x, float $shape, float $scale): float

Returns the probability density at x, where the random variable follows the gamma distribution of which the shape parameter is shape and the scale parameter is scale.

Elenco dei parametri

x: The value at which the probability density is calculated
shape: The shape parameter of the distribution
scale: The scale parameter of the distribution

Valori restituiti

The probability density at x or false for failure.
