R-script and metadata accompanying data for 'Carcase grading reflects the variation in beef yield - A multivariate method for exploring the relationship between beef yield and carcase trait'. The aim of study is to evaluate and describe how changes in conformation, fat cover, weight and category contribute to change in multivariate yield. In addition, the effect of breed was studied, in order to estimate the degree to which breed accounts for variance in the multivariate yield as a confounding factor. The files availably here is the metadata as a description of the rawdata, together with the R-code used for analysis.
