In jwolfson/medMatch: Sensitivity analysis for mediation effects via matching.

Description

Internal function for calculating matching-based bounds for the NDE.

Usage

getBounds(DAT, inds, Gamma = 1, Psi = Gamma, effect = "ATT")

Arguments

DAT	A data frame containing columns for the treatment (Z), outcome (Y), potential mediator (S and S.cat), and baseline covariates (W1, W2, ...)
inds	A vector of indicators for the bootstrap.
Gamma	The sensitivity parameter controlling the odds ratio between the true and estimated odds of a discordant pair favoring the treatment.
Psi	The sensitivity parameter controlling the odds ratio between the true and estimated odds of a pair being discordant.
effect	The causal effect to be estimated. Can be ATT or ATC.

Details

This function is called by the bootstrap procedure in the main DeltaBounds function.

Value

A vector of three elements containing:

1. The estimated lower bound

2. The estimated value

3. The estimated upper bound
