stats_cdf_negative_binomial

Calculates any one parameter of the negative binomial distribution given values for the others

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

Returns the cumulative distribution function, its inverse, or one of its parameters, of the negative binomial 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, r, and p denotes cumulative distribution function, the number of failure, the number of success, and the success rate for each trial, respectively.
