Only four items per twin are shown. Λ1.1 denotes the factor loading for the first item, for twin 1. A1.1 denotes the residual variance due to A for the first item, for twin 1. ra.1=1.0 or 0.5 and denotes the twin correlation for the residual components due to A for the first item, etc. rc.1=1.0 and denotes the twin correlation for the residual components due to C for the first item, etc.
