According to VAN TASSELL & VAN VLECK (1996), this occurs when the error value added to the mean estimate of the a posteriori distribution of the heritability coefficient does not change the estimate value.
It is noteworthy that this measure is considered small when its value, added to the mean estimate of a posteriori distribution of the heritability coefficients, does not change the estimated value up to the second decimal place (VAN TASSELL & VAN VLECK, 1996).
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).
