We investigate the rate of convergence of so-called n-point Gauss type quadrature formulas to integrals of the form R 1 0 f(x)d(x) where is a general distribution function on 0; 1) and where f is analytic and admits a Laurent expansion in C n f0g. The general results are then applied in the special case where d(x) = x a expf?(x + x ?)gdx, a 2 R and 2 (1=2; 1).
