The matrices have a repeating structure, with 10 replications per block. Each block contains N1 replications of condition Small followed by N2 of condition Large. The proportion of N1 to N2 is varied to simulate replication-count asymmetry, from N1 = 1 and N2 = 9 (high asymmetry) to N1 = 5 and N2 = 5 (fully symmetric).
