Figure 1.— — The rank of (right axis) and the relative computation time (left axis) along chicken chromosome 1. The relative computation time is the ratio of the total number of flops used in AI-REML for the inversion of V by the reduced method and direct inversion. This is [n³ + N_red(n²k +3nk²)]/[N_fulln³/2], where N_red and N_full are the number of iterations until convergence using Π_red and Π, respectively, n is the number of observations, and k is the rank of Π_red. A marker position is given by an “X” along the x-axis.
