Table 4 Concordance between predictions and data

From: A simple model based on mutation and selection explains trends in codon and amino-acid usage and GC composition within and across genomes

  1. Each entry is the correlation coefficient between the predicted and observed values for the 64 codons (above the diagonal) or 21 amino acid sets (below the diagonal) for archaea and bacteria (left) and eukaryotes (right). See Figure 5 for an example (the graph for the first entry on the second column: note that the graph shows R2, not R).
