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

The following table lists the return value and parameters by which. CDF, x, k, and theta denotes cumurative distribution function, the value of the random variable, and the shape and the scale parameter of the gamma distribution, respectively.
