Comparisons are made of various techniques used to identify gamma-ray burst repeaters in BATSE data. The effectiveness of each test is examined when BATSE positional errors and incomplete sky sampling are folded into the data analysis. Techniques studied include the two-point angular correlation function, the nearest neighbor statistic, and the farthest neighbor statistic. Comments are made concerning the observed incidence of repeaters in BATSE's First Burst Catalog. This work has been supported by NASA grants NAG8-192 and NRA 92-OSSA-17.
