Odds ratio (eβ) and mean square error obtained in 1,000 simulations using the three different approaches, NAIVE, THRES and LC (see text for a description of each). Results are given for different scenarios, varying the number of individuals (I), the proportion of individuals with each copy number status (π), the odds ratio (eβ), and the variance for CNV quantitative measurements.
