stats_dens_laplace — Probability density function of the Laplace distribution

説明

stats_dens_laplace(float $x, float $ave, float $stdev): float

Returns the probability density at x, where the random variable follows the Laplace distribution of which the location parameter is ave and the scale parameter is stdev.

パラメータ

x: The value at which the probability density is calculated
ave: The location parameter of the distribution
stdev: The shape parameter of the distribution

戻り値

The probability density at x or false for failure.
