Abstract: | In this paper we consider experimental settings where treatments are being tested in b
1 rows and b
2 columns of sizes k
1i
and k
2j
, respectively, i=1,2,..., b
1, j=1,2,..., b
2. Some sufficient conditions for designs to be E-optimal in these classes are derived and some necessary and sufficient conditions for the E-optimality of some special classes of row and column designs are presented. Examples are also given to illustrate this theory. |
