Example: Multiple Comparisons Test

A multiple-comparisons analysis is performed using data discussed by Kirk (1982, pp. 123-125). The results show that there are three groups of means with three separate sets of values: (36.7, 40.3, 43.4), (40.3, 43.4, 47.2), and (43.4, 47.2, 48.7).

using System;
using Imsl.Stat;
using PrintMatrix = Imsl.Math.PrintMatrix;

public class MultipleComparisonsEx1
{
	public static void  Main(String[] args)
	{
		double[] means = new double[]{36.7, 48.7, 43.4, 47.2, 40.3};
		
		/* Perform multiple comparisons tests */
		MultipleComparisons mc = 
			new MultipleComparisons(means, 45, 1.6970563);
		
		new PrintMatrix("Size of Groups of Means").Print(mc.Compute());
	}
}

Output

Size of Groups of Means
   0  
0  3  
1  3  
2  3  
3  0
