Suggested Calibration Estimators of Finite Population Total for Cluster Sample - (I)

In survey sampling, the use of auxiliary information can greatly improve precision estimates population total and/or means. Calibration estimation has developed into an important field research in sampling where plays role. this paper, calibration estimator for cluster with equal clusters have been introduced to variance aid and proposed estimator. Six distances measures, presented approach estimators are a simulation study conducted compare between performance against Horvitz-Thompson using R statistical package.
