This study introduces a novel recursive algorithm for spatial cluster detection, improving upon existing methods by searching a wider range of subregions. The new approach enhances the power and accuracy of identifying disease outbreaks and other spatial event clusters.

Area of Science:

Spatial analysis
Geographic information systems
Epidemiology

Background:

Spatial cluster detection identifies subregions with concentrated events, crucial for disease outbreak analysis.
Current methods often struggle with the computational complexity of analyzing numerous subregions.

Purpose of the Study:

To develop a more efficient and comprehensive algorithm for spatial cluster detection.
To evaluate the performance of the new recursive algorithm in terms of detection power and accuracy.

Main Methods:

A novel recursive algorithm was developed to search a richer set of spatial subregions beyond simple grids or rectangles.
Simulation experiments were conducted to assess the algorithm's effectiveness.

Main Results:

The recursive algorithm explores a broader range of subregions compared to traditional methods.
Simulation results indicate improved detection power and accuracy in identifying spatial clusters.

Conclusions:

The developed recursive algorithm offers a more effective approach to spatial cluster detection.
This method has significant implications for pinpointing disease outbreaks and other spatially concentrated events.
