Local spatial tests

These spatial cluster detection methods are used to investigate disease clusters near a particular area. They can be thought of as tests that attempt to answer the question: Within the study area can one consider particular geo-referenced observations to be members of statistically significant spatial clusters (location is implied)?1 Or, are the neighbors of a particular observation, within some distance, closer together (or have an attribute of greater or lesser magnitude) than chance would have it?
