stats_cdf_laplace
(PECL stats >= 1.0.0)
stats_cdf_laplace — Calculates any one parameter of the Laplace distribution given values for the others
Description
stats_cdf_laplace ( float $par1 , float $par2 , float $par3 , int $which ) : float
Returns the cumulative distribution function, its inverse, or one of its parameters, of the Laplace distribution. The kind of the return value and parameters (par1
, par2
, and par3
) are determined by which
.
The following table lists the return value and parameters by which
. CDF, x, mu, and b denotes cumulative distribution function, the value of the random variable, and the location and the scale parameter of the Laplace distribution, respectively.
which | Return value | par1 | par2 | par3 |
---|---|---|---|---|
1 | CDF | x | mu | b |
2 | x | CDF | mu | b |
3 | mu | x | CDF | b |
4 | b | x | CDF | mu |
