stats_cdf_gamma

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

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

Returns the cumulative distribution function, its inverse, or one of its parameters, of the gamma 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, k, and theta denotes cumulative distribution function, the value of the random variable, and the shape and the scale parameter of the gamma distribution, respectively.

par1The first parameter

par2The second parameter

par3The third parameter

whichThe flag to determine what to be calculated

Returns CDF, x, k, or theta, determined by . which
