Simulation univariate study. Student t-test of mean and variance differences between the lines selected by the univariate Kullback-Leibler (KL), Continuous Ranked Probability Score (CRPS) and Linear-Linear (LinLin) loss functions vs. lines selected under the standard selection method (Std), after 20 replications of the simulated breeding program. The selected proportions were the top 10% and top 30% of the candidates, and the means and variances were compared at the 10th selection cycle
