A 4-class solution provided the best fit to the offspring data based on fit statistics from the Akaike Information Criterion (AIC) and the sample-size-adjusted Bayesian Information Criterion (ABIC), which were lower for the 4 class (AIC=4322.21, ABIC=4363.98) than for either the 3 (AIC=4335.47, ABIC=4366.42) or the 5-class solutions (AIC=4325.38, ABIC=4377.98). The most likely class membership probability was used for class assignment. Fifty-three percent of the sample (n=443) was assigned to Class 1, 31% (n=260) was assigned to Class 2, 8% (n=69) to Class 3 and 7% (n=59) to Class 4.
