The a posteriori distribution means of the variance components obtained using the threshold model were higher than those obtained by the linear model (Table 3).
Since the iteration number was high enough and the likelihood function overcame the a priori information, which began to have little importance in the interferences, the a posteriori distribution may become less symmetrical if the lack of information is assumed (Table 3).
