A random question for people with science leanings:

I need a probability distribution, but its shape isn't really known. That inclines me to use a gaussian as a generic, because most things are gaussian.

However, it can't produce negative values. What would you use?

Truncate the gaussian below zero? Fold negative values back to positive? Something like a chi-square distribution that looks gaussian once the mean is far from zero?

After some coffee I'll rephrase that, if I can make those who read it not lose IQ points. *sigh* It's been a day.

Yes, it has. I hate teaching about finite automata...
