Geospatial Analytics for Social Good - Understanding Nigeria Water functional and non-functional water point rate

Geospatial analytics hold tremendous potential to address complex problems facing society. In this study, you are tasked to apply appropriate global and local measures of spatial Association techniques to reveals the spatial patterns of Not Functional water points. For the purpose of this study, Nigeria will be used as the study country.
