Abstract
In recent years, many statistical methods have been proposed for detecting
excesses of rare diseases, i.e., clusters, in space or in space-time. Most of
these methods deal with case-event or individual-level data and are designed
to detect clusters with shape close to circles. In this study, adapting the
idea of Choynowski (1957), a two-stage simulation-based approach is proposed
to detect both circular and non-circular clusters with aggregate or
group-level data. The proposed cluster-detection method will be used to
compare with Spatial scan statistic (Kulldorff, 1995) and Flexible scan
statistic (Tango, 2005), two frequently used methods. Computer simulation is
used to illustrate the validity of the proposed approach. In addition, the
cancer mortality and fertility data of Taiwan area are also used to
demonstrate the proposed test.
Key words. Cluster detection, Rare disease, Aggregate data, Monte Carlo
Simulation, Permutation Test.
