Figure 3.

Percentage of interactions detected (or null hypotheses of no interaction rejected) by each of the four tests in the simulation settings corresponding to 3 × 3 and 9 × 5 array from 1000 simulated datasets with N = 3600. Details are described in Section 6.1. The top label within each box represents the true simulation model whereas the horizontal axis labels indicate the tests carried out. The error variance ${\sigma }_e^2$ is set at 4 in all cases. Results based on cell-means model.
