  1. The table shows results for the switch error rate by, respectively, our phase update algorithm (see Appendix C for pseudocode) in the IBD column, the BEAGLE algorithm in the BGL column, and the combined approach in the BOTH column for a dataset simulated by using N = 10000 as the size of the original population, T = 100 as the number of generations for which the population was simulated, n as the size of the family sampled, t = 5 as the number of generations for which the family was simulated, L as the genetic length in centimorgans of the haplotypes simulated, and s = 400 as the number of SNPs in the haplotype.
