Path diagram of the Cholesky decomposition. Variables enclosed in circles are latent variables. The red arrows connecting A1–A4, C1–C4, and E1–E4 to SPEQ age 16 represent the sources of shared variance between autistic traits and SPEQ subscale scores. The blue arrows, which connect A5, C5, and E5 to SPEQ age 16, represent the residual variance in SPEQ subscales scores. The black arrows represent the paths between autistic traits at each age.
