Parameters 
Description 
[In] TVec X 
Stores data which is assumed to be exponentialy distributed. 
out double mu 
Returns exponential distribution parameter estimator. 
ref double[] PCIMu

double Alpha 
Confidence interval percentage.

Example

The following example generates 100 random standard exponentially distributed values and then uses ExponentFit routine to extract used Mu parameter:

using Dew.Math; using Dew.Stats; using Dew.Stats.Units; namespace Dew.Examples; { private void Example() { Vector vec1 = new Vector(1000,false); // first, generate 1000 randomly beta distributed // numbers with parameter mu=4.13, and default seed StatRandom.RandomExponent(4.13,vec1,-1); double estmu; double[] cimu = new double[2]; // Now extract the mu and its 95% confidence intervals. Statistics.ExponentFit(vec1,out estmu,out cimu, 0.05);
