A spatial accuracy assessment of an alternative circular scan method for Kulldorff's spatial scan statistic

By S. Read, P.A. Bath, P. Willett and R. Maheswaran

Abstract

This paper concerns the Bernoulli version of Kulldorff’s spatial scan statistic, and how accurately it identifies the exact centre of approximately circular regions of increased spatial density in point data. We present an alternative method of selecting circular regions that appears to give greater accuracy. Performance is tested in an epidemiological context using manifold synthetic case-control datasets. A small, but statistically significant, improvement is reported. The power of the alternative method is yet to be assessed
