Entropy-balancing weights (Hainmueller 2012)

Routes to the shared native entropy-balancing solver (smallstats_native.R): control units are reweighted so their covariate means match the treated means exactly (ATT).

Usage

morie_weight_entropy(data, treatment, covariates)

Arguments

data

Data frame.

treatment

Binary treatment column (0/1).

covariates

Covariate column names.

Value

A morie_weight object (ATT estimand).
