Normal distribution in Java

[Christian]

Hi NG

I need to get a normal distribution based on a mean and variance. How do I
do that in Java?

Is there a standart packet to use?

There is a single, simple formula. Next time try Google. For now take
a look at http://mathworld.wolfram.com/NormalDistribution.html

Re: Normal distribution in Java

Did you try java.util.Rando m? There is a method called nextGaussian that
produced a random value from a normal distribution of mean 0.0 and variance
1.0.

From there, generating numbers from a normal distribution of mean m and
variance v is an easy task.
