Randomized graph cluster randomization

Journal of Causal Inference, 2023
The global average treatment effect (GATE) is a primary quantity of interest in the study of causal inference under network interference. With a correctly specified exposure model of the interference, the Horvitz–Thompson (HT) and Hájek estimators of the

New logarithmic type imputation techniques in presence of measurement errors

Alexandria Engineering Journal, 2023
Several imputation techniques have been constructed to sort out the missing data issue. However, there are few papers that address the missing data issue in measurement error (ME).

Estimation of finite population variance under post-stratified randomized response technique

Ain Shams Engineering Journal
Stratified sampling is commonly employed to enhance the precision of the estimators by ensuring adequate representation from each stratum. However, constructing a sampling frame may be impractical or infeasible due to the complex and heterogenous ...
