The Infant Health and Development Program (IHDP) benchmark introduced by Hill (2011): real covariates describing children and their mothers from a randomised experiment, combined with a simulated outcome, which provides ground-truth treatment effects. The treatment is intensive, high-quality childcare and home visits; the (simulated) outcome mimics future cognitive test scores.

ihdp_train

x0-x5

Continuous covariates (standardised).

x6-x24

Binary covariates.

t

Binary treatment indicator (0/1).

y

Continuous (simulated) outcome.

tau
