Good quality point sets and error estimates for moving least square approximations
Applied Numerical Mathematics, 2003The author discusses the construction of moving least square approximations. Error estimates in Sobolev spaces are given. It is discussed that the condition number of the star of nodes could be used as a good measure for the quality of the distribution of the nodes and patches.

On Discrete Polynomial Least-Squares Approximation in Moving Time Windows
1999The paper presents a modification algorithm for least-squares approximations in moving time windows for equidistant discrete data. Properties of discrete shift and difference operators are used to derive fast square-rootand division-free algorithms, especially suitable for implementation on DSPs, for some particular discrete weights.
