  • ASSIGNING CONFIDENCE VALUES TO AUTOMATED PROPERTY VALUATIONS BY USING THE NON-TYPICAL PROPERTY CHARACTERISTICS OF THE PROPERTIES
    Publication number: 20130144796
    Abstract: Automatically assigning confidence ratings to properties valued by an automated valuation model. A value confidence model determines a set of typical property characteristics for properties in a geographic area, automatically determines a deviation from the set of typical property characteristics for a candidate comparable property, and assigns a confidence factor to an automated valuation of the candidate comparable property based upon the deviation.

  • MODEL-BASED SCORING OF COMPARABLE PROPERTIES BASED UPON THEIR APPROPRIATENESS FOR USE AS COMPARABLES FOR A SUBJECT PROPERTY
    Publication number: 20130132287
    Abstract: Automatically rating comparable properties by accessing property data and comparable assessment information, in which a regression is performed, on to model the relationship between the comparable-appropriateness of the property data and explanatory variables.

  • PROPERTY VALUE ESTIMATION WITH CATEGORICAL LOCATION VARIABLE PROVIDING NEIGHBORHOOD PROXY
    Publication number: 20120215703
    Abstract: Model-based property value estimation with that implements a categorical location variable providing a neighborhood proxy. A regression models the relationship between sale price and a set of explanatory variables. These explanatory variables include a location variable that is defined at a level of granularity such that the location variable acts as a proxy for location within a neighborhood. An infill process remedies the effects of insufficient amounts of location variable data.
