stats_cdf_noncentral_f

stats_cdf_noncentral_f

Calculates any one parameter of the non-central F distribution given values for the others

float **stats_cdf_noncentral_f** float $par1 float $par2 float $par3 float $par4 int $which

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 (, , , and ) are determined by . par1``par2``par3``par4``which

The following table lists the return value and parameters by . 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.
