Probabilities.ExpCDFInv Method (double, double)

Exponential distribution point percent function (PPF).

Syntax
C#
Visual Basic
public static double ExpCDFInv(double p, double Mu);
Parameters 
Description 
double p 
Probability, real positive value on closed interval [0,1]. 
double Mu 
Defines distribution rate parameter. Mu must be a positive real value. 

the exponential distribution point percent function (PPF). The parameter Mu must be a positive real value and the probability y must lie on the interval [0,1], otherwise the result is NAN.

The inverse exponential cumulative distribution function is defined by the following equation: 

 

The result of ExpCDFInv is the value such that there is a probability p that an observation from an exponential distribution with parameter Mu will fall in the range [0,result].
