A Review on Optimum Covariate Designs

Abstract

Study of optimality of designs with covariate models started with Lopes Troya (1982a, 1982b). Later on, it was considered by a number of authors. Notable among them are Das et al. (2003) and Rao et al. (2003). In a series of papers, Dutta, Das and Mandal considered different design set-ups and proposed optimum covariate designs where the covariate effects were estimated with global optimality. The paper contains a short review of the present developments in this connection.
