Even when a parameter set (v, k, λ) satisfies the necessary conditions for the existence of a Balanced Incomplete Block (BIB) design, the actual design may not exist or its existence may be unknown.

Certain balanced incomplete block designs are such that a double grouping of blocks into sets made up of complete replications is possible, with a corresponding reduction in the variance of interblock ...

Several important series of balanced incomplete block designs can be derived from orthogonal factorial designs. One is the series on balanced lattice of Yates (1936); refer to page 396 of Cochran and ...

Analysis of variance is most often used for data from designed experiments. You can use the PLAN procedure to construct designs for many experiments. For example, PROC PLAN constructs designs for ...
