Java normal distribution

Question

I\'m trying to simulate the arrival of fans to a stadium. The system itself, I believe it won\'t be a problem, but, the arrival of the fans follows a normal distribution.

Answer 1

I suggest you to use apache math: http://commons.apache.org/math/ , look here for more information: http://commons.apache.org/math/userguide/stat.html

Answer 2

nextGaussian() will draw samples from a normal distribution with mean 0 and std-deviation 1, so if you want mean 1 hour and std-deviation 15 minutes you'll need to call it as nextGaussian()*15+60.

From the docs for Random.nextGaussian():

Returns:
the next pseudorandom, Gaussian ("normally") distributed double value with mean 0.0 and standard deviation 1.0 from this random number generator's sequence
