For more than a decade, it has been known that many common behavior genetics models for a single phenotype can be estimated as multilevel models (eg, van den Oord 2001; Guo …
Twin and family studies have historically aimed to partition phenotypic variance into components corresponding to additive genetic effects (A), common environment (C), and …
Many behavior genetics models follow the same general structure. We describe this general structure and analytically derive simple criteria for its identification. In particular, we find that …
Genome-wide association studies (GWAS) have successfully identified common variants associated with BMI. However, the stability of aggregate genetic variation influencing BMI …
Behavior genetics is a field that studies how our genes and environment contribute to differences in behavior and traits among individuals. Traditionally, twin studies have long …
It is now just over 30 years since the International Statistical Genetics Workshop (commonly referred to as “The Boulder Workshop” or just “The Workshop”) found a home in Boulder …
A novel method has been proposed that extends the use of regularisation to structural equation modelling (SEM). Traditionally, SEM is used in psychological research to estimate …
Genome-wide association studies (GWAS) have successfully identified common variants associated with BMI. However, the stability of genetic variation influencing BMI from midlife …
