Delineating Objective Market Segments using Geographically Weighted Regression (GWR) and GIS tools.

Producing neighborhood and market segment hierarchies are essential for the development of location-based influences on property value. Capturing and quantifying spatial neighborhood effects to delineate and segment potential market areas can be a very tedious process. This session will provide guidance on a methodology that allows for the development of a standardized location factor that will allow for the visualization of areas that have desirable or less desirable influences on value. These location factors can then be run through a machine learning grouping algorithm to maximize the differences between groupings while preserving the similarities within groupings. The results of this methodology can be utilized by appraisers and analysts as an objective method to reconcile market segments for use in valuation cost and market models of residential properties.

Uncovering Patterns in Valuation Data Using Business Intelligence tools and GIS.

Visualization using interactive graphs, charts, and maps makes business intelligence tools powerful and robust applications for valuation professionals to understand the patterns within property data. This session will demonstrate basic data exploration, visualization and analysis capabilities using a powerful BI tool within the context of a real analysis. Learn how to dig deeper into your property and sales data to find inconsistencies and anomalies, as well as understand the distributions, patterns, and relationships of important variables that contribute to value within your jurisdiction.
