Mass Appraisal Valuation Modeling in R or SPSS - Session 7/8
Friday, March 26 – 1:00 – 4:00 PM Central

This workshop will introduce key concepts and practices for mass appraisal valuation modeling over eight sessions. Each session will include theoretical instruction, a hands-on lab and a Q&A wrap-up. Participants will learn how to build mass appraisal valuation models using a typical set of CAMA data using either R or SPSS.

Participants will learn how to review, evaluate, and clean data; transform CAMA data for use in models; conduct time trend analysis and create time adjustments within a model; build and evaluate an additive model and build and evaluate a multiplicative model. In the lab sessions, participants will practice writing and executing model code.

By the end of this workshop, participants should understand how regression models are used in the mass appraisal of real estate and be able to build models using attributes found in most CAMA data files. They will leave with libraries of code that can be used to transform data and build regressions models.
