stats_cdf_cauchy — Calculates any one parameter of the Cauchy distribution given values for the others

Descrição

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

Parâmetros

par1: The first parameter
par2: The second parameter
par3: The third parameter
which: The flag to determine what to be calculated

Valor Retornado

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