Floating point Data generator

Question

Is there a program or source code for data generation?

I want a data generator for Java. (Language does not matter, if I can get the result file)

I want a correlated data, anti-correlated data, independent data.

I want a data generator program that has

input : min, max, data-distribution (ex., independent, anti-correlated, correlated, Gaussian, Poisson ... ), dimension, # of points (n)

output : n points that follows given data-distribution.

Thank you :)

Answer 1

You can change the interval of the generated numbers with some simple math:

Random r=new Random();
floatx=(r.nextFloat()%(max+min))-min;

The java random class also has an option to return gaussian distributed values.
