estimators as its particular cases, including the Stein rule family of estimators proposed by James and Stein (). In the context of linear regression mod-els, the family of double k-class estimators was proposed under the assumption of spherical or homoskedastic disturbances. Later, Wan and Chaturvedi (). required to achieve a specified precision in estimating a loss probability. Because this means that the number of portfolio revaluations is also reduced by a factor of or more, it results in a very large reduction in the computing time required for Monte Carlo estimation of VAR. The rest of this article is organized as follows. I am looking for references of studies that show how to use Monte Carlo simulations to compare different estimators for any given parameter of any probability distribution (for example, comparing the MLE vs. the method-of-moments estimator, for . Estimating Integrals Via Monte Carlo • The beneﬁt of Monte Carlo is with higher dimension multiple integrals, and with extremely complex integrals (like those in rendering) • It also provides an easy (but slow!) ground truth to compare against approximations • Rendering!

Savin proposes to test the Monte Carlo hypothesis by a method free from these criticisms. Like Anderson, he uses a Chi-squared goodness of fit test but he works with the NBER data used by McCulloch and concentrates on expansions. He too finds that the Monte Carlo hypothesis cannot be rejected. McCulloch () replied to Savin (), arguing. Most improvements to Monte Carlo methods are variance-reduction techniques. Antithetic Resampling Suppose we have two random variables that provide estimators for, and, that they have the same variance but that they are negatively correlated, then will provide a better estimate for because it's variance will be smaller.. This the idea in antithetic resampling (see Hall, ). II. MONTE CARLO TECHNIQUES FOP. ESTImATING UNCERTAINTY In the previous section, it was noted that cost estimate uncer-tainty results from two primary sources--requirements and cost-estimating uncertainty. The relationship between the system cost uncertainty. Next: Exercise One dimensional Up: Monte Carlo integration Previous: Simple Monte Carlo integration The Monte Carlo method clearly yields approximate results. The accuracy deppends on the number of values that we use for the average.

Evaluations using Monte-Carlo simulations show that standard errors estimators, assuming a normally distributed population, are almost always reliable. In addition, as expected, smaller sample sizes lead to less reliable.
