Popis: | RAS is a spatial data analysis system integrated with ARC/INFO, in which we combine spatial data analytical techniques with GIS visual techniques to provide a flexible and convenient tool in regional studies. In this paper, we introduce some traditional spatial statistical analysis techniques such as the Moran I, as well as newly developed exploratory data analysis techniques such as local Moran and local Geary statistics. Criteria are suggested for the identification of spatial association by combining the local Moran and local Geary. The usefulness of these techniques in identifying and quantifying spatial associations within economic regions is illustrated using data for southern counties and census tracts. |
