): 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.
