Note. There were 24, 26, and 28 df s for Models 1, 2, and 3, respectively; therefore, 2 df s for the comparison between Models 1 and 2. L² = Likelihood-ratio chi-square test statistic. BD, CD, and GD refer to the main effect of the same behavior at 17 and 29 months of age, and of the child’s gender, respectively.

Model 1 is CD, BGD with 20 df s.
