Statistics.BinomFit Method (TVec, TSample, TVec, TVec, TVec, TSample)

Calculate parameters for binomial distributed values.

public BinomFit(TVec X, double n, TVec p, TVec Low, TVec High, double alpha);

Parameters

Parameters	Description
X	Stores data which is assumed to be binomial distributed.
n	Defines binomial distribution n parameter.
p	Returns binomial distribution p parameter, estimated at each X value.
Low
High	p (1-Alpha)*100 percent confidence intervals. Each pair of Low and High values defines lower and upper CI for corresponding p value.
alpha	Confidence interval percentage.

C# Example

The following example generates 100 random Weibull distributed values and then uses WeibullFit routine to extract used a and b parameters: The following example generates 100 binomial distributed values and then uses BinomFit routine to extract p parameter

using Dew.Math;
using Dew.Stats;
using Dew.Stats.Units;
namespace Dew.Examples;
{
  private void Example()
  {
    Vector vec1 = new Vector(1000,false);
    Vector LowInt = new Vector(0);
    Vector HighInt = new Vector(0);
    StatRandom.RandomBinom(35,0.25,vec1);
    // Now extract p-s and its 100*(1-Alpha)
    // confidence intervals.
    double p;
    Statistics.BinomFit(vec1,35,out p,LowInt,HighInt,0.05);
    // vector p holds the p for each element in vec1,
    // vectors LowInt and HighInt hold the lower and upper conf. int. limit
    // for each element in p
  }
