Notes

1

ΔBICj, 0–1 is the difference in the BIC statistics between the 0-D and 1-D models (i.e. the null model and the 1-D alternative) for the indicated variable. Positive values indicate that the higher dimensional model performs better statistically, with higher positive values indicating greater significance. The rankings indicate the relative significance among the 80 variables in the male model.

2

ΔBICj, 0–3 is the difference in the BIC statistics between the 0-D and 3-D models (i.e. the null model and the 3-D alternative) for the indicated variable, which is interpreted like ΔBICj, 0–1.
