In evalHTE: Evaluating Heterogeneous Treatment Effects

Estimation of the Grouped Average Treatment Effects (GATEs) in Randomized Experiments

Description

Estimates grouped average treatment effects from a continuous score.

Usage

GATE(D, tau, Y, ngates = 5, centered = FALSE)

Arguments

D	Binary treatment indicator (0 or 1).
tau	Continuous score vector.
Y	Outcome vector.
ngates	Number of groups (at least 2).
centered	Whether to center outcomes before estimation.

Details

Uses GATE for inference.

Value

A list with group estimates gate and standard errors sd, ordered by increasing score.
