**Spatial Statistical Sites**

A wide array of sites contain interesting spatial statistical content. Obviously, spatial statistics is a subset of statistics with many applications. Application areas include agriculture (yields between two adjacent plots are more similar than those far away), astronomy (gravity introduces dependence), biology (plants may repel or cluster), economics (wages vary regionally), geography (the study of such dependences), geology (minerals tend to cluster), manufacturing (defects tend to cluster), and real estate (houses in the same neighborhood share similarities). The increasing availability of georeferenced data coupled with the importance of space have led to an increased interest in spatial statistics.

All applications areas have their canonical tools for modeling space. Interestingly, some of these fields have developed similar techniques. For example, Best Linear Unbiased Prediction (BLUP) was developed in geology and in economics independently. While geology recognized this quickly as an important spatial paradigm, Goldberger’s development of BLUP in economics was seen as primarily a time series tool. Equally interesting, some of the fields developed ad hoc techniques for spatial modeling. Statistical reasoning provides a framework for assessing these ad hoc techniques.
