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′Ω−1X) and price change matrices (X′Y and X′Ω−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.
