Typical techniques include antithetic variables, control variables, conditional Monte Carlo, importance sampling (IS), stratified sampling, quasi-Monte Carlo (QMC) and so on . IS is useful in the estimation of rare-event probabilities [8] , and the cross-entry method, a classic IS technique, has been applied in reliability evaluation [9] The Monte Carlo method is performed by repeatedly running a model on a simulated outcome based on varying inputs; the inputs are uncertain and variable. A common but powerful strategy for modelling uncertainty is to randomly sample values from a probability distribution. This allows you to create thousands of input sets for your model This is the more generalized form of the Monte Carlo estimator, and the one you should remember (if there's only one equation to remember from the last two chapters, it is the one).
