Overview of this book

Spatial statistics has the potential to provide insight that is not otherwise available through traditional GIS tools. This book is designed to introduce you to the use of spatial statistics so you can solve complex geographic analysis. The book begins by introducing you to the many spatial statistics tools available in ArcGIS. You will learn how to analyze patterns, map clusters, and model spatial relationships with these tools. Further on, you will explore how to extend the spatial statistics tools currently available in ArcGIS, and use the R programming language to create custom tools in ArcGIS through the ArcGIS Bridge using real-world examples. At the end of the book, you will be presented with two exciting case studies where you will be able to practically apply all your learning to analyze and gain insights into real estate data.

Finding outliers in real estate sales activity using the Cluster and Outlier Analysis tool


The next tool we'll examine is the Cluster and Outlier Analysis tool. This tool, in addition to performing hot spot analysis, identifies outliers in your data. Outliers are extremely relevant to many types of analysis. The tool starts by separating features and neighborhoods from the study area. Each feature is examined against every other feature to see if it is significantly different from the other features. Likewise, each neighborhood is examined in relationship to all other neighborhoods to see if it is statistically different than other neighborhoods. In this exercise, you'll learn how to use the Cluster and Outlier Analysis tool to find outliers (hot spots located in areas of cold spots and cold spots located in areas of hot spots).

Preparation

Let's get prepared before using the Cluster and Outlier Analysis tool for finding outliers in real estates sales activity by performing the following steps...
