On A-efficient treatment-control designs constructed by cyclic and generalized cyclic designs
Abstract We consider a treatment-control design in the design of experiments. We give two constructions of treatment-control designs, using cyclic and generalized cyclic designs. We apply the constructions to efficient cyclic designs given by John and efficient generalized cyclic designs given by Hall and Jarrett and we give a list of A-efficient treatment-control designs obtained by using a computer programing in the practically useful ranges of the parameters.
