Least Squares Problems with Absolute Quadratic Constraints
This paper analyzes linear least squares problems with absolute quadratic constraints. We develop a generalized theory following Bookstein’s conic-fitting and Fitzgibbon’s direct ellipse-specific fitting. Under simple preconditions, it can be shown that a minimum always exists and can be determined by a generalized eigenvalue problem. This problem is numerically reduced to an eigenvalue problem...
متن کاملOn Weighted Structured Total Least Squares
In this contribution we extend our previous results on the structured total least squares problem to the case of weighted cost functions. It is shown that the computational complexity of the proposed algorithm is preserved linear in the sample size when the weight matrix is banded with bandwidth that is independent of the sample size.
متن کاملLeast squares problems with inequality constraints as quadratic constraints
Linear least squares problems with box constraints are commonly solved to find model parameters within bounds based on physical considerations. Common algorithms include Bounded Variable Least Squares (BVLS) and the Matlab function lsqlin. Here, we formulate the box constraints as quadratic constraints, and solve the corresponding unconstrained regularized least squares problem. Box constraints...
متن کاملErratum to: Adaptive matching pursuit with constrained total least squares
After publication of our work [1], we noticed that equations (41) and (42) (in Appendix 1) were incorrect. This does not affect resulting equations. The correct equations are below:

for an unknown vector of parameters β0 and an unknown univariate function τ(·). This model is implied by many important limited dependent variable and regression models, as discussed in Ruud (1986) and Stoker (1986). Consistent estimators for β0, up to an unknown scale factor, have been developed by Ruud (1986), Stoker (1986), Powell, Stock, and Stoker (1989), Ichimura (1993), and others. In th...
