It is well known that the upper bounds of the weighted Moore–Penrose inverse play a fundamental role in the perturbation analysis for the weighted linear least squares problem. In this note, we provide a sharp estimation for , (1) Thus norm estimations for the weighted Moore–Penrose inverses of the acute perturbations can be improved uniformly.
