Comparison of model choice criteria: a simulation study. Simulation results for different values of the true number of QTL, K, and the number of observed QTL, q. The vertical bars indicate the probability that the best model selected by the criterion is the true model. The open circles, respectively the dotted lines, represent the mean, respectively the 0.1% and 0.9% quantiles, of the ratios MSEP(2)/MSEP(1) for each criterion.
