and only two animals swapped places for BFAT compared with the result from the full
PC analysis. However, only the top four and six animals were the same for WWG and
PWG, respectively, compared with the full PC analysis, indicating more re-ranking was
observed in WWG due to the reduction in variance. In practice, models with reduced
ranks are usually applied in the analysis of many traits as in Meyer (2007), resulting
in no re-ranking in the top animals, which are mainly of interest.
