Robust and Least Squares Orthogonal Mapping: Methods for the Study of Cephalofacial Form and Growth.

Abstract

A method is presented for the description and analysis of cephalofacial form and growth using two-dimensional coordinate data. The procedure permits the identification of shape differences at specific cephalofacial coordinate locations without reliance upon conventional cephalometric landmarks. The resulting size-standardized coordinates can be analyzed by statistical methods for further data exploration. Two methods of shape transformation--least squares amd robust fitting--are described and compared. An example of the utility of the technique for cephalofacial growth studies is provided. (Author)
