Subgroups

We used machine learning to identify distinct profiles of initial FAST score and growth (slope) with respect to child, family, and attendance factors that influence a child's early development.

Subgroup is the numeric code for a distinct set of children identified using our methodology.

Mother Highest Education and Birth Country, Health/Social, Service, & Attendance information defines the subgroup: children with specific values for these characteristics constitute the subgroup.

Not Predictive characteristics did not differentiate children in this subgroup on FAST score and growth

Mean Initial FAST score, Mean Slope (FAST score / month in VPK), and projected Final Score for the subgroup; also in bubble and bar plots

Shows factors like Provider Type (Public): 1.639, Alcohol Use during Pregnancy: 0.627, etc.

Values below represent the expected increase (positive) or decrease (negative) in FAST slope associated with each predictor for the selected terminal node. For categorical predictors, values represent expected change due to membership in that group. For continuous predictors, values represent expected change for one-unit increase in that predictor. Values were only computed for predictors with sufficient variability within this subgroup.
