Session 5 of the Mass Appraisal Modeling series is now live.
We just locked in the final and most sophisticated OLS model of
the progressive series — high-cardinality ZIP-code location modeling,
disciplined outlier removal, application of the Principle of Parsimony,
near-normal residuals, and practical BLUE status. Plus a first look at how the
official assessment roll compares to both sale prices and the model.
This is the Champion.
Session 6 brings the modern ML-friendly One-Hot Encoding Challenger into the ring for a head-to-head ratio study. The finals are coming.
The Executive Summary is free for everyone. Paid subscribers can access the full session.
