Summary:
We present general and particular analyses under a mixed linear model resulting from the construction of a non-orthogonal split-split-plot (SSP) design and proper randomization performed (see, Ambroży and Mejza, 2013). The design was generated by some group divisible block designs. Attention is paid to optimal statistical properties with respect to the efficiency of estimation of some groups of basic and any contrasts in both the generating and final designs. The considerations are illustrated with simulated data from an experiment with grain yields of winter wheat.
