A flexible spatial scan test for case event data
نویسنده
چکیده
A new method is proposed for identifying clusters in spatial point processes. It relies on a specific ordering of events and the definition of area spacings which have the same distribution as one-dimensional spacings. Then the spatial clusters are detected using a scan statistic adapted to the analysis of one-dimensional point processes. This flexible spatial scan test seems to be very powerful against any arbitrarily-shaped cluster alternative. These results have applications in epidemiological studies of rare diseases. © 2008 Elsevier B.V. All rights reserved.

Spatial analysis of influenza incidence in EMRO using flexible scan statistics
Introduction: Influenza is an infectious and severe respiratory disease. It is one of the major problems of public health. In order to determine the spatial distribution and areas with over-expected of a disease including influenza, it can be effective in identifying environmental hazards and fair distribution of health services. In this study, the geographical distribution of the influenza and...
متن کاملA flexibly shaped space-time scan statistic for disease outbreak detection and monitoring
BACKGROUND Early detection of disease outbreaks enables public health officials to implement disease control and prevention measures at the earliest possible time. A time periodic geographical disease surveillance system based on a cylindrical space-time scan statistic has been used extensively for disease surveillance along with the SaTScan software. In the purely spatial setting, many differe...
متن کاملTESTING FOR “RANDOMNESS” IN SPATIAL POINT PATTERNS, USING TEST STATISTICS BASED ON ONE-DIMENSIONAL INTER-EVENT DISTANCES
To test for “randomness” in spatial point patterns, we propose two test statistics that are obtained by “reducing” two-dimensional point patterns to the one-dimensional one. Also the exact and asymptotic distribution of these statistics are drawn.
متن کاملFamily of power divergence spatial scan statistics
The classical spatial scan test, which derived by maximizing the likelihood ratio statistic over a collection of cluster candidates, is widely used in spatial cluster detection. As the likelihood ratio statistic is only a special case in the family of power divergence (PD) goodness-of-fit statistics, the classical spatial scan test is extended to the family of PD spatial scan tests. Therefore, ...
