In evalHTE: Evaluating Heterogeneous Treatment Effects

This function use individualized treatment rule to identify exceptional responders. The details of the methods for this design are given in Imai and Li (2023).

Description

This function use individualized treatment rule to identify exceptional responders. The details of the methods for this design are given in Imai and Li (2023).

Usage

URATE(D, tau, Y)

Arguments

D	A vector of the unit-level binary treatment receipt variable for each sample.
tau	A vector of the unit-level continuous score. Conditional Average Treatment Effect is one possible measure.
Y	A vector of the outcome variable of interest for each sample.

Value

A list that contains the following items:

rate	The estimated vector of URATE of length Y.
sd	The estimated vector of standard deviation of URATE.
