constEffect {randomizationInference}

Potential Outcomes With Constant Treatment Effects

Description

Calculates potential outcomes under modified assignments, according to the specified constant treatment effect(s).

Usage

constEffect(y, w, w_new, poOptions)

Arguments

y

a vector or matrix of outcomes.

w

a vector or matrix of assignments.

w_new

a vector or matrix of modified assignments.

poOptions

a list of options for calculating potential outcomes. poOptions$tau is a number or numeric vector denoting the constant treatment effect(s).

Value

A vector of potential outcomes under the modified assignments.
