چکیده انگلیسی
Suppose that Y=(Yi) is a normal random vector with mean Xb and covariance Ï2In, where b is a p-dimensional vector (bj),X=(Xij) is an nÃp matrix. Given a family D of D-optimal designs, a design Z in D is chosen that is robust in the sense that Z is D-optimal in D when the components Yi are dependent: for iâ iâ², the covariance of Yi,Yiâ² is Ïâ 0. Such designs Z merely depend on the sign of Ï. The general results are applied to the situation where Xijâ{-1,1}; this corresponds to a factorial design with -1,1 representing low or high level, respectively, or corresponds to a weighing design with -1,1 representing an object j with weight bj being placed on the left and right side of a chemical balance, respectively.
