Example: The Probability Distribution Functions

Examples of the probability distribution functions are exercised. Their use in this example typifies the manner in which other functions in the Pdf class would be used. 
using System;
using Pdf = Imsl.Stat.Pdf;

public class PdfEx1
{
    
    public static void  Main(String[] args)
    {
        
        // Beta
        double x = .5;
        double pin = 12.0;
        double qin = 12.0;
        double result = Pdf.Beta(x, pin, qin);
      Console.Out.WriteLine("Pdf.Beta(.5, 12., 12.) is {0,5:0.0000}", result);

      // binomial
      int k = 3;
      int n = 5;
      double prob = .95;
      result = Pdf.Binomial(k, n, prob);
      Console.Out.WriteLine("Pdf.Binomial(3, 5, .95) is " + result);

        
        // Chi
        prob = .99;
        n = 2;
        result = Pdf.Chi(prob, n);
      Console.Out.WriteLine("Pdf.Chi(.99, 2) is {0,5:0.0000}", result);
    }
}

Output

Pdf.Beta(.5, 12., 12.) is 3.8683
Pdf.Binomial(3, 5, .95) is 0.021434375
Pdf.Chi(.99, 2) is 0.3048
