  • Method for determining house price indices
    Patent number: 11288690
    Abstract: A method for estimating a real estate price index based on a repeat sales model.
    Type: Grant
    Filed: September 20, 2010
    Date of Patent: March 29, 2022
    Inventor: Chionglong Kuo
  • Efficient computation method for determining house price indices
    Patent number: 7983925
    Abstract: The present invention relates to an efficient computer implemented method and system for generating a home price index based on a repeat sales model by calculating the time-dimension frequency matrices (X?X and X???1X) and price change matrices (X?Y and X???1Y) directly without the need to calculate the big X and Y matrices at the dimension of the number of repeat sales. The inventive method may further be used to estimate indices for multiple geographic levels without processing an entire data set to estimate the price indices for each geographic level.

  • Method and apparatus for predicting and reporting a real estate value based on a weighted average of predicted values
    Patent number: 7305328
    Abstract: A system and method of accurately predicting and reporting a value of a property based on a weighted average of values predicted by at least two prediction models. The system and method include the steps of accessing predicted values, determined by the prediction models, for the property; determining property-specific proportional prediction error distribution information for each predicted value determined by each prediction model; assigning a weight to the predicted value determined by each prediction model by using the property-specific proportional prediction error distribution information; and generating a property-specific weighted average value based on combination of the weight and the predicted value determined by each prediction model and reporting the property-specific weighted average value to minimize prediction error during prediction of the property value.
