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 ...

PROC MIXED can fit a variety of mixed models. One of the most common mixed models is the split-plot design. The split-plot design involves two experimental factors, A and B. Levels of A are randomly ...

The multivariate analysis of variance for a one-factor experiment in a randomized blocks design with several observations per cell usually assumes equality of the covariance matrices of the errors. A ...

We have already seen that varying two factors simultaneously provides an effective experimental design for exploring the main (average) effects and interactions of the factors 1. However, in practice, ...
