[AM7-5] Local measures of spatial association

Unlike global measures of spatial association, local measure of spatial association identifies the locations of clusters. Typical measures include the local indicator for spatial autocorrelation (LISA) or the local Moran’s index whose summation is proportional to the global Moran’s index. The spatial scan statistics has also been the commonly used method to detect local clusters.
