Descrierea
$par1
, float $par2
, float $par3
, int $which
) : float
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 cumulative distribution function, the value of the random
variable, the degrees of freedom and the non-centrality parameter of the distribution,
respectively.
