Free Parameters (NP): 104, Loglikelihood (LL): −38,665.09, Akaike’s Information Criterion [AIC; (Akaike, 1976)]: 77,538.19, Bayesian Information Criterion (BIC): 78,072.05). Secondary model: The primary model was segregated by offspring sex (N (males):631, N (females): 622, NP: 180, LL: −37,626.34, AIC: 75,612.68, BIC: 76,536.67). All predictors were checked for multicollinearity by means of tolerance statistics. Values of the Variance Inflation Factor (VIF) were all well below 10 (i.e., all less than 1.21) and tolerance statistics were all well above 0.20 (i.e., all >0.80), indicating that there is no collinearity within these data (e.g., Field, 2009). To correct for multiple comparisons, the Benjamini–Hochberg procedure (see McDonald, 2014) controlling for the false discovery rate (FDR) was implemented and an FDR of 0.05 was used. Descriptive statistics for key variables in the study for the overall sample and separately for male and female offspring are reported in Table 1. Bivariate correlations are reported in Table 2.
