THE APPLICATION OF PROJECTION METHOD FOR LEAST SQUARES PROBLEMS
摘要
Abstract
Projection operators or projectors play an important role in numerical linear algebra, particularly in iterative methods for solving various matrix problems. The method of least squares is a standard approach in regression analysis. The projection method is exploited to deduce the normal equation of linear least squares problems. Furthermore, it is easy to use the projection method to solve the weighted linear least squares problems.关键词
