Estimating the mean difference assignment
WebThe average treatment effect (ATE) is a measure used to compare treatments (or interventions) in randomized experiments, evaluation of policy interventions, and medical trials.The ATE measures the difference in mean (average) outcomes between units assigned to the treatment and units assigned to the control.
