Abstract:

Weapon accuracy assessment for elliptical normal miss distances is accomplished through the use of statistical tolerance circles. While tolerance circles for circular normal miss distances have been available in the literature for some time, such circles for the elliptical normal case have not been available heretofore. They are formulated for the bivariate normal distributions with unequal variances. The procedure is approximate in that it provides circles which contain at least 100P of the population with approximately vice exactly 100gamma confidence. Its closeness is examined in detail and is shown to provide confidence which is very close to 100gamma. The procedure is extended to the uncorrelated k dimensional normal distribution but the closeness is not studied for k 2. It application is general and is not restricted to miss distance data.
