On the weighting method for mixed least squares–total least squares problems

Numerical Linear Algebra with Applications, 2017
SummaryIt is well known that the standard algorithm for the mixed least squares–total least squares (MTLS) problem uses the QR factorization to reduce the original problem into a standard total least squares problem with smaller size, which can be solved based on the singular value decomposition (SVD).

Weight coefficients in the weighted least squares method

Numerical Analysis and Applications, 2015
Summary: We consider a problem of estimating some parameters of linear mathematical models. It is found that by choosing weight coefficients in the least squares method, one can obtain solutions by minimizing any penalty functions of a wide class, including Hölder norms.
