stats_cdf_noncentral_t

(PECL stats >= 1.0.0)

stats_cdf_noncentral_tCalculates any one parameter of the non-central t-distribution give values for the others.

Description

float stats_cdf_noncentral_t ( float $par1 , float $par2 , float $par3 , int $which )

Returns the cumulative distribution function, its inverse, or one of its parameters, of the non-central t-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, nu, and mu denotes cumurative distribution function, the value of the random variable, the degrees of freedom and the non-centrality parameter of the distribution, respectively.
