In this study, we compare two methods of generating grid points to enable efficient geographic cluster detection when the original geographical data are prohibitively numerous. One method generates uniform grid points, and the other employs quad… read more… M. A spatial scan statistic. Commun Stat Theory Meth 1997;26:1481–96. 6. Kulldorff M. Tango T, Park P.
