Some sufficient conditions for the E- and MV-optimality of block designs having blocks of unequal size
In this paper we consider experimental situations in which v treatments are to bee tested in b blocks where \(b_ i\) blocks contain \(k_ i\) experimental units, \(i=1,...,p\), \(k_ 1<k_ 2<...<k_ p\). The idea of a group divisible (GD) design is extended to that of a group divisible design with unequal block sizes (GDUB design) and then a number of results concerning the E- and MV-optimality of GD designs are generalized to the case of GDUB designs.
