Finding the secret sauce: The portability or non-portability of regression models
No full textModels are built to replicate decisions and behaviors for specific markets. While there are some commonalities that allow model structures, data transformations, code and even adjustment coefficients to be used across jurisdictions, most markets have unique features and dynamics that prevent simply porting a model from one area to another. This presentation discusses the importance of seeking out and understanding the \u27secret sauce\u27 that drives each market, and presents examples of both portable and non-portable model elements
See More From the Air: Commercial Property Assessment Becomes Easier With High-Resolution Aerial Imagery (Strategic Partner Thought Leader Session)
No full textBecause of parking facilities, varied lot sizes and other design features, commercial properties can be more difficult to assess than residential properties. Aerial imagery provides a helpful view of those features. Plus, the measurements and data imbedded in aerial imagery are extremely accurate. Using imagery, assessors can reduce, or even eliminate, time-consuming and costly site visits, while also maintaining fair and equitable tax rolls. Hear real-life examples of counties using imagery to improve the commercial assessment process

An Analytical Take on Mass Appraisal
No full textIn late 2021 emerging policy options re-envigored the Valuation Office Agency’s interest in Mass Appraisal. It had been 15 years since previous modelling, which was largely outsourced. Since then, the technology had been decommissioned and much of the expertise moved on. However, the Agency had grown its own analytical team, but in other areas. What could analysts, using the latest analytical platforms, such as R, offer? And how has that shaped our mass appraisal modelling – particularly the exploration of different methodologies? The path was uncertain, but the VOA has begun the journey to rekindle our mass appraisal capability, with analysts at the forefront
The Use of New, Existing and Changing Technology in the Assessment Field
No full textThis session will focus on the use of new and enhanced Technology across the Assessment field.
