Thanks Nick,
Now what i meant about mean and sd whithin a range is that I need the
distributions to be generated randomly. That is, that the mean and
standard deviations be randomly chosen from a range. The end result is
a set of random numbered distribution with randomly chosen mean and
standard deviation.
Does this make any sense??
Thanks again.
