摘要
This paper is concerned with the problem of computing approximate Doptimal design for polynomial regression with analytic weight function on a interval [m(0) - a, m(0) + a]. It is shown that the structure of the optimal design depends on a and weight function. Moreover, the optimal support points and weights are analytic functions of a at a = 0. We make use of a Taylor expansion to provide a recursive procedure for calculating the D-optimal designs.
