The control variates method is a variance reduction technique used in Monte Carlo methods. It exploits information about the errors in estimates of known quantities ...
The main variance reduction methods are common random numbers; antithetic variates; control variates; importance sampling; stratified sampling; moment matching; conditional Monte Carlo; and quasi random variables (in Quasi-Monte Carlo method) For simulation with black-box models subset simulation and line sampling can also be used. Under these ...
The antithetic variates technique consists, for every sample path obtained, in taking its antithetic path — that is given a path {, …,} to also take {, …,}.The advantage of this technique is twofold: it reduces the number of normal samples to be taken to generate N paths, and it reduces the variance of the sample paths, improving the precision.

A Nigerian man has been extradited to the US to face charges in the “sextortion” of a South Carolina teen who died by suicide in 2022. Prosecutors allege the scammer posed as a young woman ...
USAID delivers billions of dollars in humanitarian aid, funding that advocates say provides a critical lifeline to more than 100 countries at only a small fraction of the overall federal budget.
