Comparison of Average Error Rates of the PL Algorithm, the PGS Algorithm, and Clark’s Algorithm, for Two Real Data Sets

	Average Error Rate (Standard Error) forb
Algorithma	ACEc (L = 52)	CFTRd (L = 23)
PL	.19 (.003)	.39 (.008)
PGS	.36 (.004)	.48 (.009)
Clark's	.27 (.000)	.47 (.018)

^aThe EM algorithm was excluded from the comparison because it cannot handle more than 15 heterozygous loci in the data.

^bAverage error rates were defined as the number of erroneous phase calls divided by the total number of phase calls.

^cAverage error rates were obtained by 100 independent runs of each algorithm.

^dAverage error rates were for 100 data sets generated by randomly permuting 56 of the 57 complete haplotypes reported by Kerem et al. (1989).
