Here is an example for this, ><http://www.mathstatica.com/examples/> >but they use special package (I don't have it) Although I did not check the URL, I would assume the package being used is mathStatica which offers a variety of enhancements over the statistical routines that are distributed with Mathematica. The simplest way to generate pseudo-random numbers would be to use the standard add-ons. For example, if I wanted pseudo-random numbers from a normal distribution I would do <<Statistics`; Random[NormalDistribution[0,1]] Similar syntax works for a number of common distributions. If you need something other than one of the distributions available, then you will need to write your own code. Vol 2 of Knuth's Seminumerical Algorithms describes a number of ways to generate pseudo-random numbers from arbitrary distributions. -- To reply via email subtract one hundred and four
