Best performing models are in italics. Error was measured by holding out a portion of the data (out-of-sample), fitting models to in-sample data, and then measuring predictive accuracy on the observations held out. With forward, backward, and in-range, analyses were performed by randomly selecting 50% of the children and subsequently holding out 20% of their data
