(PECL stats >= 1.0.0)

stats_dens_laplace — Probability density function of the Laplace distribution

Description

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

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.

Parameters

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

Return Values

The probability density at x or FALSE for failure.
