Fitting of fixed regression curves with different residual variance structures for Nellore cattle growth modeling

Fitting of fixed regression curves with different residual variance structures for Nellore cattle growth modeling

Different polynomial functions were tested for mean trajectory modeling with different residual variance structures. A total of 15,148 weight records of 3,115 Nellore Mocho cattle with ages between 1 and 660 days, raised in northern Brazil. First, the mean trajectory of cattle growth curve was fitte...
