Regional Taxonomy Using Trend-Surface Coefficients and Invariants

Environment and Planning A, 1977, vol. 9, issue 8, 945-955

Abstract: The coefficients of polynomial trend surfaces are a function of the origin and orientation of the grid coordinate system chosen for the analysis. This hampers the interregional comparison of such surfaces. In this paper, some transformations of the calculated surface coefficients are defined which are invariant of grid origin and orientation. Their use is illustrated with an application to some housing density data for fifteen US metropolitan areas.
