Optimal Experimental Designs

open access: yesThe Annals of Mathematical Statistics, 1966
Abstract : This paper presents a number of results concerning the theory of the optimal design of experiments initiated and principal developed by Elfving, Kiefer and Wolfowitz. The paper contains approximately half expository and half new material. The proofs are mostly new and presented in a unified manner.
