Hedonic Algorithm & Spatial Kernel Details
This engine integrates a spatial hedonic pricing model combined with an inverse-distance kernel density estimator (KDE) over open-source cadastral & OpenStreetMap telemetry:
V_hat = β_0 + β_area·Area + β_lot·Lot + β_beds·Beds + β_baths·Baths + γ_loc·(1/(d_transit + ε)) + δ_school·SchoolRank + Σ (w_i · P_comp_i)
w_i = exp( - (d_geo_i² / 2Ï_geo² + d_sqft_i² / 2Ï_sqft² + Ît_i / Ï) ) / Z
Every location shift on the map dynamically recalculates distances to mass transit hubs, school polygons, and reweights nearby comps using anisotropic Gaussian decay kernels.
