- All Implemented Interfaces:
NormalizedRandomGenerator
public class UniformRandomGenerator extends java.lang.Object implements NormalizedRandomGenerator
This class implements a normalized uniform random generator.Since it is a normalized random generator, it generates values from a uniform distribution with mean equal to 0 and standard deviation equal to 1. Generated values fall in the range [-√3, +√3].
- Since:
- 1.2
