stats_cdf_cauchy

(PECL stats >= 1.0.0)

stats_cdf_cauchyCalculates any one parameter of the Cauchy distribution given values for the others

説明

stats_cdf_cauchy(
    float $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 cumulative distribution function, the value of the random variable, the location and the scale parameter of the Cauchy distribution, respectively.

Return value and parameters
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

パラメータ

par1

The first parameter

par2

The second parameter

par3

The third parameter

which

The flag to determine what to be calculated

戻り値

Returns CDF, x, x0, or gamma, determined by which.
