Abstract:

In this paper, we consider the exact D-optimal design problem for linear trigonometric regression models with intercept and without intercept on a partial circle. Dette, Melas, and Pepelyshev (2001) found explicit solutions of approximate D-optimal designs for trigonometric regression models with intercept on a partial circle. The exact optimal designs are determined by means of moment sets of trigonometric functions. It is shown that the structure of the optimal designs depends only on the length of the design interval.
