stats_dens_gamma — Probability density function of the gamma distribution

Beschreibung

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.

Parameter-Liste

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

Rückgabewerte

The probability density at x or FALSE for failure.
