Abstract: Continuous property-level location effects may be determined by generating property-level location effect functions that map location coordinates to property-level location effect values. Each property-level location effect function corresponds to a sub-region of a larger region, the larger region being a region to which a hedonic equation of an automated valuation model corresponds. Each of the property-level location effect functions may be generated by fitting a set of data points that correspond to the sub-region for which the function is being generated. The set of data point to which a given function is fitted are based on the differences between model-estimated values and actual values (e.g., sales prices) for each of the properties located in the corresponding sub-region and in at least one adjoining sub-region. The property-level location effects functions are continuous and vary within their respective sub-region according to property-level changes in location effect.

Abstract: A method and system for computing an amenity score for any arbitrary point in a given geographic area. The amenity score may take into account a variety of amenity types and an optional list of user-prioritized amenity types, to compute a score that measures the overall amenity availability for that location. The amenity score may be determined by identifying amenities, assigning a unit function to each identified amenity, summing unit functions to obtain an integrated function for each amenity type, and combining the integrated functions into an amenity score function.
