Increase in power through multivariate analyses

Autor: S, Schmitz, S S, Cherny, D W, Fulker

Publikováno v: Behavior genetics. 28(5)

Power to detect genetic and environmental influences increases not only with sample size but also with the number of measurements through longitudinal and/or multivariate designs, if those measurements correlate with each other. Power simulations are

Combined linkage and association sib-pair analysis for quantitative traits

Autor: Stacey S. Cherny, John K. Hewitt, D. W. Fulker, Pak C. Sham

Publikováno v: American journal of human genetics. 64(1)

SummaryAn extension to current maximum-likelihood variance-components procedures for mapping quantitative-trait loci in sib pairs that allows a simultaneous test of allelic association is proposed. The method involves modeling of the allelic means fo

Multivariate path analysis of specific cognitive abilities data at 12 years of age in the Colorado Adoption Project

Autor: M, Alarcón, R, Plomin, D W, Fulker, R, Corley, J C, DeFries

Publikováno v: Behavior genetics. 28(4)

A parent-offspring multivariate conditional path model was fitted to specific cognitive abilities data from the Colorado Adoption Project (CAP) when the offspring were 12 years of age. The sample included 175 adoptees, 175 sets of adoptive parents, 1

Adoption results for self-reported personality: evidence for nonadditive genetic effects?

Autor: R, Plomin, R, Corley, A, Caspi, D W, Fulker, J, DeFries

Publikováno v: Journal of personality and social psychology. 75(1)

Twin studies consistently indicate moderate genetic influence on individual differences in personality as assessed using self-report questionnaires, with heritability estimates typically about 40%. In this first analysis of self-report personality da

Exploring the genetic and environmental etiology of high general cognitive ability in fourteen- to thirty-six-month-old twins

Autor: S A, Petrill, K, Saudino, S S, Cherny, R N, Emde, D W, Fulker, J K, Hewitt, R, Plomin

Publikováno v: Child development. 69(1)

Although numerous theories have attempted to explain the origins of high general cognitive ability (g), the genetic and environmental etiology of high g during infancy and early childhood has not previously been investigated. We report results of a t
