ArcGIS Tutorial : Regression Analysis

This tutorial demonstrates how regression analysis has been implemented in ArcGIS, and explores some of the special considerations you want to think about whenever you use regression with spatial data.

Regression analysis allows you to model, examine, and explore spatial relationships, to better understand the factors behind observed spatial patterns, and to predict outcomes based on that understanding. Ordinary Least Squares regression (OLS) is a global regression method. Geographically Weighted Regression (GWR) is a local, spatial, regression method that allows the relationships you are modeling to vary across the study area.

The tutorial begins by setting the scenario: Authorities in your community are spending a large portion of public resources responding to 911 emergency calls. Projections indicate population in the area is going to double over the next 10 years. If you can better understand some of the factors contributing to high call volumes now, perhaps you can recommend strategies to help reduce 911 calls in the future.
