FIVE-FACTOR CENTRAL COMPOSITE DESIGNS ROBUST TO A PAIR OF MISSING OBSERVATIONS
Vice-Chanselor, Islamia University Bahawalpur, Pakistan.
Abstract: Missing Observations in Central Composite Designs (c.c.d) are well investigated since the development of Minimaxloss criterion presented by Akhtar and Prescott . 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.
Keywords: Missing values, central composite designs, robust designs, minimaxloss criterion.
