stats_cdf_f

stats_cdf_f

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

float **stats_cdf_f** float $par1 float $par2 float $par3 int $which

Returns the cumulative distribution function, its inverse, or one of its parameters, of the F distribution. The kind of the return value and parameters (, , and ) are determined by . par1``par2``par3``which

The following table lists the return value and parameters by . CDF, x, d1, and d2 denotes cumulative distribution function, the value of the random variable, and the degree of freedoms of the F distribution, respectively.

par1The first parameter

par2The second parameter

par3The third parameter

whichThe flag to determine what to be calculated

Returns CDF, x, d1, or d2, determined by . which
