For a given block size, replication, and number of treatments, it is well known that a balanced incomplete block design, if one exists, is of maximum efficiency. We take the case of an even number of ...

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 ...

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 ...

DURING the course of recent work at the West African Cacao Research Institute, it became necessary to evaluate the products of small-scale fermentations of different types of cacao. Hitherto, samples ...
