Three kinds of effective error bounds of the quadrature formulas withmultiple nodes that are generalizations of the well known Micchelli-Rivlinquadrature formula, when the integrand is a function analytic in the regionsbounded by confocal ellipses, are given. A numerical example which illustratesthe calculation of these error bounds is included.
