Description
$par1
, float $par2
, float $par3
, int $which
) : float
Returns the cumulative distribution function, its inverse, or one of its parameters,
of the Cauchy 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, x0, and gamma denotes cumurative distribution function, the value of the random
variable, the location and the scale parameter of the Cauchy distribution, respectively.
