An analytical method based on the theory of statistical probability is developed for separating regional from local potential field effects. It is applied to an objective test on an artificial problem, as well as to a gravity survey that has already been the subject of studies of other averaging methods. It succeeds in both tests with good accuracy, and points up the danger of arbitrariness in the use of numerical methods.
