The least-squares S-wave phase shifts of the scattering of electrons by simple, Yukawa and static potentials are compared with the exact phases. Additionally, Kohn's, Rubinow's and the least-squares methods (LSM) are used for calculating the S-wave phase shifts of e+-H elastic scattering by employing trial and test-function spaces which allow for virtual positronium excitation. The results are in good agreement with those of other authors.
