Datasets in the Fragile Families Challenge. During the Fragile Families Challenge, participants used the background data (measured from child’s birth to age 9 y) and the training data (measured at child age 15 y) to predict the holdout data as accurately as possible. While the Fragile Families Challenge was underway, participants could assess the accuracy of their predictions in the leaderboard data. At the end of the Fragile Families Challenge, we assessed the accuracy of the predictions in the holdout data.
