In txshift: Efficient Estimation of the Causal Effects of Stochastic Interventions

Estimate Auxiliary Covariate of Full Data Efficient Influence Function

Description

Estimate Auxiliary Covariate of Full Data Efficient Influence Function

Usage

est_Hn(gn_exp, gps_bound)

Arguments

gn_exp	An estimate of the exposure density (a generalized propensity score) using the output provided by est_g_exp.
gps_bound	numeric giving the lower limit of the generalized propensity score estimates to be tolerated (default = 0.05). Estimates less than this are truncated to this or 1/n. See bound_propensity for details.

Details

Compute an estimate of the auxiliary covariate of the efficient influence function required to update initial estimates through logistic tilting models for targeted minimum loss estimation.

Value

A data.table with two columns, containing estimates of the auxiliary covariate at the natural value of the exposure H(A, W) and at the shifted value of the exposure H(A + delta, W).
