stats_cdf_noncentral_chisquareCalculates any one parameter of the non-central chi-square distribution given values for the others

Açıklama

stats_cdf_noncentral_chisquare(
    float $par1,
    float $par2,
    float $par3,
    int $which
): float

Returns the cumulative distribution function, its inverse, or one of its parameters, of the non-central chi-square 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, k, and lambda denotes cumulative distribution function, the value of the random variable, the degree of freedom and the non-centrality parameter of the distribution, respectively.

Return value and parameters
which Return value par1 par2 par3
1 CDF x k lambda
2 x CDF k lambda
3 k x CDF lambda
4 lambda x CDF k
