Since the efficiency factors compare the designs to a (hypothetical) orthogonal design, values of 100% are not possible in this case. The OPTEX procedure includes facilities for examining the ...
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.
While the analysis of variance test statistic F in a balanced incomplete block design without randomization is a constant under the Fisher model, i.e., a linear model without technical errors, and it ...
