The objective of this analysis is to obtain insight into whether positionally close pairs of GRBs are due to repetitions, clustering, or random chance. We consider the Brightness Ratio Distribution (BRD) of pairs of events. Here, brightness is used as a generic term for any quantity related to the observed intensity of an event. The BRD has the interesting property that if one can select pairs whose components are at the same distance-such as, by considering only close-together pairs-then the distance dependence ``drops out'' of each brightness ratio and the BRD becomes narrower because its width no longer has a component caused by the sources' differing distances. We have begun to apply this analysis to the BATSE events for which location and brightness data are available, comparing the BRD for close-together event pairs to the BRDs for the other (presumedly unrelated) pairs. Preliminary results do not show any clear indication that close-together pairs are related. However, this work is at a very early stage with regard to optimizing the method and understanding its properties.
