Besag-Newell’s And Kulldor’s Spatial Scan Methods in Detecting Spatial Clustering

Abstract:

The Besag-Newell and Kulldor’s Spatial Scan are used to detect the spatial clustering of malaria incidence of the 177 barangays in the 11 island municipalities of Tawi-Tawi province. ClusterSeer and SaTScan are the two (2) specialized clustering software that processed the data. The data analysis for the Besag-Newell’s method resulted in 51 local clusters using ClusterSeer and the same result of 51 clusters using Kulldor’s Spatial Scan method. The QGIS visualizes these results, thus showing the geographical locations of malaria incidence in Tawi-Tawi province. It was recommended that for those who are fascinated to study more about detecting spatial clustering using Spatial and Space-time Scan statistics, the researcher recommends that if ever they preferred to use these methods, they have to use some statistical software for the analysis. Also, encourage them to provide another way of interpreting the test’s significance aside from the Monte Carlo randomization method to lead them more to an appropriate test.
