Estimators

Step-by-step tutorials for using estimators in nmar package including both data.frame and survey design objects

Empirical Likelihood

Demonstrates the empirical likelihood estimator for Not Missing at Random outcomes implemented in the NMAR package, targeting the full-data mean under the Qin–Leung–Shao (2002) model. Includes data-frame and survey-design usage, auxiliary constraints, and bootstrap variance.
