Traditional Regression Analysis

The term traditional regression analysis implies any multivariate linear regression models in the form of Y = Xb + e, where bold letters are used because they represent matrices or vectors (a special type of matrix). When dealing with a categorical dependent variable, binary (or multinomial) logistic regression is our choice. When applying these models on a CHES (e.g., often spatially explicit) basis, special care has been paid to potential spatial autocorrelation among data records: knowing data at one record (location) would automatically shed light upon knowledge about data at nearby or adjacent records or locations. This is a violation of a key assumption in regard to independence among data records in regression analysis.

One way to handle this problem is to subsample the data such that the selected records or data points are less or minimally subject to spatial autocorrelation. We conduct this subsampling process through two primary ways of 1) random sampling or 2) selecting data points that are apart from one another at a distance that is not less than the range of the corresponding semivariogram. More recent efforts have been devoted to the spatial filtering approach in terms of the Getis filtering or eigenvector spatial filtering methods. Below are several CHES-related papers that use traditional regression analysis to understand human or landscape processes and a few books that introduce the basics of regression analysis.
