Boxplots of percentage of misclassified observations calculated from 100 simulated samples from model (b) when θR = (ρR, ℓR), with ρR = 0.75, 0.5, and 0.25 in rows 1, 2, and 3, respectively; and ℓR = 3, 2, and 1 in columns 1, 2, and 3, respectively. In each group of 12 boxes, the first four are for n1 = n2 = 10 and k = 2, the next four are for n1 = n2 = 25 and k = 2, and the last four are for n1 = n2 = 25 and k = 1. In each group of four boxes, the data are transformed by Q̂−1 (first box), R−1 (second box), or T−1 (third box), or are untransformed (fourth box).
