Suppose that for a randomized block design, there are c blocks and r treatments. The observation ij y for treatment i in block j is missing. Let G represents the grand total without the missing value, T represents the total for treatment i without the missing value, and B represent the total for block j without the missing value. Denote the missing observation by x . Find the expression for x in terms of G, T and B.
