stats_cdf_exponential — Calculates any one parameter of the exponential distribution given values for the others
Description
Returns the cumulative distribution function, its inverse, or one of its parameters,
of the exponential distribution. The kind of the return value and parameters
(par1 and par2) are determined by
which.
The following table lists the return value and parameters by which.
CDF, x, and lambda denotes cumulative distribution function, the value of the random
variable, and the rate parameter of the exponential distribution, respectively.

| 3 | lambda | x | CDF |
Parameters
par1- The first parameter
par2- The second parameter
which- The flag to determine what to be calculated
Return Values
Returns CDF, x, or lambda, determined by which.
