Enhancing Dengue Fever Modeling Through a Multi-scale Analysis Framework – A Case Study in the Central Valley of Costa Rica
… rates of dengue fever. While GIS and statistical analysis have been used in research studies, agent-based modeling has not been applied to the study of dengue. This study emphasizes how traditional macro level GIS analysis and the implementation of a micro-level dengue fever agent-based model can …
