WebSep 9, 2010 · In the RRBLUP method, the simulated variance components were used as the true variance in the analyses. The ith marker variance was calculated from σ gi2 = σ a2 / N, whereσ a2 is the total additive genetic variance, as proposed by Meuwissen et al. [1]. WebInstalling r-rrblup from the conda-forge channel can be achieved by adding conda-forge to your channels with: conda config --add channels conda-forge conda config --set channel_priority strict Once the conda-forge channel has been enabled, r-rrblup can be installed with: conda install r-rrblup
