  1. Computing times in parentheses use an allele frequency of 0.5 for all markers
  2. Groups: the model had genetic groups; Groups + J1: the model had genetic groups and a single J factor; Groups + JQ: the model had genetic groups and group-wise J factors; reg, dense: regression coefficients for genetic groups and J factors in a dense matrix; reg, sparse: regression coefficients for genetic groups in a sparse matrix and J factors in a dense matrix; QP: genetic groups and J factors by QP transformation
