Figure 2. Developmental Changes in Genetic and Environmental Influences on Deviant Peers at Ages 15, 18, and 21.

Figure 2

This figure is a standardized path diagram of the full, sex-constrained Cholesky decomposition model for deviant peers with 95% confidence intervals for the parameters shown in the model. Path coefficient estimates have been squared and represent the proportion of variance in deviant peers accounted for by the components. Ai = variance attributable to additive genetic effects; Ci = variance attributable to shared environmental effects; Ei = variance attributable to nonshared environmental effects.
