From this random sample for each result, it estimates statistical measures such as mean, standard deviation, fractiles (quantiles) and probability density curves. It generates a sample of N values or scenarios for each result variable in the model using each of the of the corresponding N points for each uncertain input.

It selects each point independently from the probability distribution for that input variable.

(Feel free to skip this if you already understand Monte Carlo and LHS.) Monte Carlo (MC) simulation generates a random sample of N points for each uncertain input variable of a model. What is Latin Hypercube Sampling?Р”Р‡irst some background. Then IРІР‚в„ўll add some key insights garnered from my own experience. Several of his complaints are specific to Crystal Ball or and donРІР‚в„ўt apply to Analytica. Let me explain why I disagree with David Vose on some issues and agree with him on others. And IРІР‚в„ўve concluded that yes -it does make sense to keep Latin Hypercube as the default method. Monte Carlo on hundreds of real-world models. Why? Are we, the makers of these simulation products naР“Р‡ve? As the lead architect of Analytica for two decades, IРІР‚в„ўve explored this question in detail. Interesting points, yet products like Analytica and Crystal Ball still provide LHS and even offer it as their default method.
