Changing results

[pprosp]

Hi all. I'm using Argo for an online course on uncertainty using Monte Carlo simulation. Uncertainty can be derived from a simple mathematical equation and the Mean and SD resulting form the software simulation. However, the latter slightly change at every simulation run after file is opened up (even though no input data or equation is changed) . While I think this should be a consequence of the randomness of values following each input's distribution (do you agree?), I'm most importantly interested to know if a way to tell Argo to keep running until Mean stabilizes exists.

To be clear, the StDev is changing, not the mean?

Also, how much change are we talking about?

What dist are you using, and how many simulations? Convergence could be an issue, but it should not be. More information would help.
