problem with Random.nextGaussian()

Question

Random.nextGaussian() is supposed to give random no.s with mean 0 and std deviation 1. Many no.s it generated are outside range of [-1,+1]. how can i set so that it gives n

Answer 1

Gaussian distribution with your parameters. is has density e^(-x^2/2). In general it is of the form e^(linear(x)+linear(x^2)) which means whatever settings you give it, you have some probability of getting very large and very small numbers.
You are probably looking for some other distribution.
