stats_cdf_noncentral_f — Calculates any one parameter of the non-central F distribution given values for the others
Descrierea
$par1
, float $par2
, float $par3
, float $par4
, int $which
) : float
Returns the cumulative distribution function, its inverse, or one of its parameters,
of the non-central F distribution. The kind of the return value and parameters
(par1, par2, par3,
and par4) are determined by which.
The following table lists the return value and parameters by which.
CDF, x, nu1, nu2, and lambda denotes cumulative distribution function, the value of the
random variable, the degree of freedoms and the non-centrality parameter of the distribution,
respectively.
