#Stunting and underweight have been defined as per World Health Organization benchmarks of measures below two standard deviations of the median Height for Age z-score (HAZ) and Weight for Age z-score (WAZ) respectively. *Government preschools in India. $p-value is based on the X 2 test for differences in proportions among categorical variables tabulated against presence in the training or test datasets, or based on Students’ t-test for continuous variables.
