Exponential cumulative distribution function (CDF).

Syntax
C#
Visual Basic
public static double ExpCDF(double x, double Mu);
Parameters
Parameters 
Description 
double x 
Function domain, real positive value or zero. 
double Mu 
Defines distribution rate parameter. Mu must be a positive scalar. 
Returns

the exponential cumulative distribution function (CDF) for parameter Mu at the value X. Parameter Mu must be greater than zero, otherwise the result is NAN.

Remarks

The exponential cumulative distribution function s defined by the following equation: 

 

The result of ExpCDF is the probability that a single observation from an exponential distribution will fall in the interval [0,x].
