Description

Whenever we use sales to measure assessment performance or to estimate value, there is an assumption that properties that sell adequately and proportionally represent unsold properties. This session presents two methods for examining this assumption, measuring the degree of generalization in a regression model, identifying properties that are not represented by sales and directly comparing performance for sold and unsold properties.
