Analytic approaches to twin data using structural equation models
The classical twin study is the most popular design in behavioural genetics. It has strong roots in biometrical genetic theory, which allows predictions to be made about the correlations between observed traits of identical and fraternal twins in terms of underlying genetic and environmental components. One can infer the relative importance of these 'latent' factors (model parameters) by struct...

متن کاملTwin-singleton differences in brain structure using structural equation modelling.
Twin studies are important to investigate genetic influences on variation in human brain morphology in health and disease. However, the twin method has been criticized for its alleged non-generalizability due to differences in the intrauterine and family environment of twins, compared with singletons. To test whether twin-singleton differences complicate interpretation of genetic contributions ...
متن کاملFitting ACE structural equation models to case-control family data.
Investigators interested in whether a disease aggregates in families often collect case-control family data, which consist of disease status and covariate information for members of families selected via case or control probands. Here, we focus on the use of case-control family data to investigate the relative contributions to the disease of additive genetic effects (A), shared family environme...
متن کاملAn empirical Assessment using structural equation Models
In a recent study, the authors reveal with structural equation models that the positive effect of information technology on generalized trust is mediated by political institutions. Although insightful, a key question remains: Is it the effectiveness and efficiency, the universality, and/or the power-sharing capacity of the state that mediates this effect? Drawing on new institutional economics,...
