Appeal Probability Model
Logistic regression on historical appeal outcomes by jurisdiction, deviation, and property type.
Appeal Probability Model
Our appeal success probability model uses logistic regression trained on historical appeal outcomes from the Cook County Board of Review. Fitted jurisdiction effects cover Cook County townships; other jurisdictions use the pooled model. Key features include:
- Jurisdiction -- appeal success rates vary widely by county
- Assessment deviation -- larger over-assessments correlate with higher success rates
- Property type -- residential vs. commercial and industrial vs. multi-family vs. vacant
- Representation -- self-represented vs. attorney
