1. How to check if sample belongs to a normal distribution using Shapiro-Wilk (original) test ?
PIVariable var = new PIVariable();
var.AddValues( new int[] { 65, 61, 63, 86, 70, 55, 74, 35, 72, 68, 45, 58 } );
PIShapiroWilk test = new PIShapiroWilk( var );
test.Evaluate();
Console.WriteLine( "W value = " + test.W );
Console.WriteLine( "p-value = " + test.PValue );
Console.WriteLine( test.ToString() );
Output:
W value = 0,971026084704613
p-value = 0,873681129394841
The sample belongs to a normal distribution -> accepted (0,05).
