Testing for Spatial Autocorrelation in Areal Data
Consider a linear model for a spatial system of n areal units, (1) , ~ (0,) Y X u u N V where both and V are unknown. The simplest procedure for specifying the covariance matrix, V , is to start by assuming that (2) 2 n V I , so that can be estimated by OLS. Given this estimate, one can then test to see whether there is sufficient spatial autocorrelation in the residuals to warran...
متن کاملSpatial Interaction and Spatial Autocorrelation: A Cross-Product Approach
A cross-product statistic is used to demonstrate that spatial interaction models are a special case of a general model of spatial autocorrelation. A series of traditional measures of spatial autocorrelation is shown to have a cross-product form. Several interaction models are shown to have a similar form. A general spatial statistic is developed which indicates that the relationship between the...
متن کاملAnalyzing Migration Phenomena with Spatial Autocorrelation Techniques
In recent times a complete lack of attention to migration phenomena, in national and global policies, led to a huge concentration of foreigners in major cities of Europe and USA. This trend has been faced without effective policies and programs. Consequently, a great opportunity has been transformed in a great threat and the word immigration is generally associated with the term social security...
متن کاملClustering multivariate spatial data based on local measures of spatial autocorrelation
A growing interest in clustering spatial data is emerging in several areas, from local economic development to epidemiology, from remote sensing data to environment analyses. However, methods and procedures to face such problem are still lacking. Local measures of spatial autocorrelation aim at identifying patterns of spatial dependence within the study region. Mapping these measures provide th...
متن کاملSpatial Autocorrelation
Glossary AutoA prefix literally meaning self; spatial autocorrelation means self-correlation, or values within a given variable are correlated, resulting in the variable being correlated with itself. Correlation A description of the nature and degree of a relationship between a pair of quantitative variables. Geary Ratio An index of spatial autocorrelation, involving the computation of squared ...
