Title Implicit scaling of linear least squares problems
Abstract We consider the solution of weighted linear least squares problems by Householder transformations with implicit scaling, that is, with the weights stored separately. By holding inverse weights, the constrained case can be accommodated. The error analysis of the weighted and unconstrained case is readily extended and we show that iterative refinement may be applied.
