Cramer-Von Mises Variance Estimators for Simulations

MetadataShow full item record
We study estimators for the variance parameter sigma(2) of a stationary process. The estimators are based on weightings yield estimators that are 'first-order unbiased' for sigma (2) We derive an expression for the asymptotic variance of the new estimators; this expression is then used to obtain the first-order unbiased estimator having the smallest variance among fixed-degree polynomial weighting functions. Although our work is based on asymptotic theory, we present exact and empirical examples to demonstrate the new estimators' small-sample robustness.

An analysis of the factors generating the variance between the budgeted and actual operating results of the Naval Aviation Depot at North Island, California Curran, Thomas; Schimpff, Joshua J. (Monterey, California: Naval Postgraduate School, 2008., 2008-06);For six of the past eight years, naval aviation depot-level maintenances activities have encountered operating losses that were not anticipated in the Navy Working Capital Fund (NWCF) budgets. These unanticipated losses ...

Trietsch, Dan (Monterey, California. Naval Postgraduate School, 1992-09); NPS-AS-92-021The Probability a Machined part will be defective increases with the variance of the machined dimensions. Even for parts within tolerance, the quality decreases with the variance. By reducing the variance of these dimensions ...
