Multidisciplinary Approaches in Genetic Studies of Human Aging and Longevity

The amount of research on human aging and longevity has been growing rapidly in recent years. Multidisciplinary approaches, which integrate classic population genetics methods with the principles of epidemiological and demographic investigation, are emerging as powerful tools for disentangling the complex gene network which modulates human lifespan. We try to summarize the different approaches ...

Bayesian model selection for group studies - Revisited

In this paper, we revisit the problem of Bayesian model selection (BMS) at the group level. We originally addressed this issue in Stephan et al. (2009), where models are treated as random effects that could differ between subjects, with an unknown population distribution. Here, we extend this work, by (i) introducing the Bayesian omnibus risk (BOR) as a measure of the statistical risk incurred ...

A family longevity selection score: ranking sibships by their longevity, size, and availability for study.

Family studies of exceptional longevity can potentially identify genetic and other factors contributing to long life and healthy aging. Although such studies seek families that are exceptionally long lived, they also need living members who can provide DNA and phenotype information. On the basis of these considerations, the authors developed a metric to rank families for selection into a family...
