FIVE-FACTOR CENTRAL COMPOSITE DESIGNS ROBUST TO A PAIR OF MISSING OBSERVATIONS

Abstract

Missing Observations in Central Composite Designs (c.c.d) are well investigated since the development of Minimaxloss criterion presented by Akhtar and Prescott [1986]. Here we investigate two missing values in different configurations of c.c.d with five factors and develop designs robust to a pair of missing observations under Minimaxloss criterion.
