Generating random integers within range with a probability distribution

Question

I have a problem where I want to generate a set of random integer values between 1 and 5 inclusive using a probability distribution.

Poisson and Inverse Gamma are t

Answer 1

I would just produce uniformly distributed random numbers then pass them into the distribution function you want, so if the distribution function was x^2

import java.util.ArrayList;

import java.util.Random;



    public class Test{

        public static void main(String args[]){
            Test t=new Test();
        }

        public Test(){

            Random rnd=new Random();

            ArrayList data=new ArrayList();

            for(int i=0;i<1000;i++){
                data.add(useFunction(rnd.nextDouble()));
            }

        }

        public double useFunction(double in){
            return in*in;
        }
    }
