Normal Distribution Formula Java


In this example I'll show you how to incorportate the normal distribution.


public class NormalDistribution {
	public static double PDF(double x) //returns the probability density function, PDF(x)
		double PDFtemp = (1/Math.sqrt(2*Math.PI)) * Math.exp(-(x*x)/2); 
		return PDFtemp;

	public static double AREA(double x)//returns the area under PDF(x) from 0 to x
		double AREAtemp = 0; //initial area under PDF(x)=0 double dx = x/1000000; //width dx
		for (double i=0; i< x; i+=dx) //for steps of size dx
			AREAtemp += dx * PDF(i+dx/2);
		} //add width*height to the area under the PDF(x) } 
		return AREAtemp;
	{ //show outputs for x=1.00, x=1.645, x=1.96, and x=2.33
