Cracking the Code of Vertical Inequity
Wednesday March 5, 2025 9:00am - 10:00am EST
Pheoris West B– 3rd Floor
This session will address the often-overlooked challenge of selecting the best market value proxy when detecting vertical inequity in mass valuations. Using a real-world dataset and Monte Carlo simulations, the presentation will demonstrate how bias varies with different proxies. Finally, a new statistical market value proxy will be introduced to improve valuation accuracy.
