The least-squares local-energy method previously described and tested in calculations on H2+ has been further tested on H2+, He, and H2. The theory of Gauss quadrature is used to provide a better basis of points over which to average the local-energy. The electronic energy is easily calculated to six significant figures for H2+ and to three or four significant figures for He and H2.
