Table 1.

Model comparison using code-length, or average negative cross-log-likelihood. Code lengths are given in bits. For Chromosome 7 data sets, SNP loci were sub-sampled in ENCODE regions to maintain an uniform coverage of the chromosome.

^(a): Population. ^(b): Number of actually polymorphic SNPs in the population considered. ^(c-h): HMM-2 for the unconstrained two-state HMM; HMM-4D for the Daly et al. HMM; LS-HOM and LS-HET for the homogeneous and the heterogeneous Li and Stephens models; GR-1 and GR-2 for the "greedy" models with context sizes 1 and 2.
