Table 3.

Expected mean squared errors for option 1 of the combined model.Table shows the expected mean squared errors associated with a combined model. This layout corresponds to a 2 × 2 × 5 factorial arrangement of sex, time, AZT and their interactions with the 80 muscle samples processed in 16 batches (blocks); each batch has 5 samples, one sample for each AZT level within a sex and a sacrifice time.
