(PECL stats >= 1.0.0)
stats_cdf_cauchy — Calculates any one parameter of the Cauchy distribution given values for the others.
Description
float stats_cdf_cauchy ( float $par1 , float $par2 , float $par3 , int $which )
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.
| which | Return value | par1 | par2 | par3 |
|---|---|---|---|---|
| 1 | CDF | x | x0 | gamma |
| 2 | x | CDF | x0 | gamma |
| 3 | x0 | x | CDF | gamma |
| 4 | gamma | x | CDF | x0 |
Parameters
par1
The first parameter
par2
The second parameter
par3
The third parameter
which
The flag to determine what to be calculated
Return Values
Returns CDF, x, x0, or gamma, determined by which.
