UV-PCA and UV-MA showed the same performance for scenarios in which there was a residual correlation between the traits. For scenarios with no residual correlation, UV-PCA performed better under negative genetic correlation and UV-MA under positive genetic correlation. They were outperformed by UV analysis of trait 1 and 2 only in case of a negative genetic correlation.
