Table 2 Comparison of model parameter estimates.

From: Linkage disequilibrium interval mapping of quantitative trait loci

Model parameter True value Empirical mean (standard error)
   T2 HAPim
x (in cM) 3.6 3.73 (5.1e-2) 3.62 (4.3e-2)
Q (0) 0.00125 0.13 (3.4e-3) 0.12 (3.0e-3)
a 1 1.02 (2.5e-2) 0.98 (2.4e-2)
d 1 0.87 (3.2e-2) 0.97 (2.7e-2)
t 100 57.9 (8.5) 53.4 (4.6)
α 1 0.92 (6.3e-3) 0.92 (6.0e-3)
  1. Empirical means (and their standard errors) of the model parameter estimates under the T2 and HAPim methods. The single nucleotide polymorphism (SNP) marker spacing was 0.25 cM, the effective population size was N = 400, and the initial association was complete.
