In the context of Monte Carlo simulation, we face a similar problem of estimate the mean \(\mathrm{E}(Y)\) of a random variable \(Y\) for which we can simulate (draw sample) from. The naive Monte Carlo estimator is the sample mean \(\overline{Y}\), similar to the naive ATE estimator \(\Delta\).Control variates provide an …
