ate.ipw: Inverse probability weighted estimation of average treatment effects

Description

This function implements inverse probability weighted (IPW) estimation of average treatment effects (ATEs), provided fitted propensity scores.

Usage

ate.ipw(y, tr, mfp)

Arguments

y

An \(n\) x \(1\) vector of observed outcomes.

tr

An \(n\) x \(1\) vector of treatment indicators (=1 if treated or 0 if untreated).

mfp

An \(n\) x \(2\) matrix of fitted propensity scores for untreated (first column) and treated (second column).

Value

one

The direct IPW estimates of 1.

est

The ratio IPW estimates of means.

diff

The ratio IPW estimate of ATE.
