RANDOMN function [message #86498]

Hi

I used the RANDOMN function to add Gaussian noise to my data like this:

noise=RANDOMN(seed,N)

When I print, the mean values of RANDOMN(seed,N) I didn't get zero but something around 0.0337187.

I expect to get something very very close to zero since the RANDOMN function returns normally-distributed, floating-points with a mean of zero. Is my assumption wrong? It's correct that the median is not zero?

Many Thanks
Mar
