Example of an Autoregressive Latent Transition Model for Psychosocial Maturity and Alcohol Use
Note. PST = proportion of time in a supervised setting. For ease of presentation, some correlations were represented with a single squared line. These were correlations between: alcohol use at age 15 and alcohol use intercept, alcohol use slope, and maturity at age 15; alcohol use intercept and alcohol use slope; maturity at age 15, maturity intercept and maturity slope; maturity intercept and maturity slope; alcohol use intercept and maturity intercept, alcohol use slope and maturity slope, and the correlations between PST and alcohol use at age 15, alcohol use intercept, alcohol use slope, maturity at age 15, maturity intercept, and maturity slope.

(a). Days to beginning maturity from emergence (2010). (b). Days to beginning bloom from emergence (2010). MG0000, a new proposed maturity group, is marked in red.

(A) Weight at maturity in kg (black circles) and age at maturity in years (red squares) for female Chinook Salmon in Lake Michigan each year for the period 1991–2008 [] in relation to the relative prey biomass (tons of Alewife/tons of Chinook Salmon). (B) Weight at maturity relative to age of maturity for these same points. In both panels, we see small changes in age at maturity and relatively large swings in size at maturity.

(A) State of maturity of females at Carelmapu locality. (B) State of maturity of males at Carelmapu. (C) State of maturity of females at Quellón locality. (D) State of maturity of males at Quellón.
