The DAC statistic: properties and use in detection of clusters

Even though its use has been limited, the DAC statistic, defined as the difference between the empirical distribution for the cases and that of the total sample, presents a great potential in detecting spatial clusters. Our previous work focused on examining its sensitivity to the location of origin and orientation of axes, and on its possible role as an instrument to detect clusters. Results indicate that the DAC statistic does not depend on the
