Figure 1

Receiver-operator characteristic curves for the simulation study. Conditions shown are: sample size 25, 50 and 100 (rows from top to bottom); length of the studied region 500 and 1000 probes (columns from left to right); proportion of samples with each effect 10, 25 and 50 percent (solid, dashed and dotted lines); and copy number effect sizes 2, 0.5 and -0.85 (line colours red, green and purple). For details about the study setup, see appendix.
