Power of Bivariate vs. Univariate Analyses for the Combined Data of Unrelated Samples and Nuclear Families (One Binary Trait and One Continuous Trait).

Notes: Three population structures are considered. For the binary trait, the OR value ranges from 12 to 1.5. For the continuous trait, the contribution of the causal site ranges from 0.0025 to 0.01. Powers are estimated on 1,000 replicates. See notes in Table 1 for sample sizes.Abbreviations: T12, the proposed test for bivariate analysis; T1, the proposed test for only the first trait; T2, the proposed test for only the second trait.
