Estimation of Population Mean with Missing Data in Stratified Random Sampling

Korakoch Silpakob, Watchareephorn Chaimongkol

Abstract


This research presents estimator of population mean with missing data in stratified random sampling developed from the estimator of population mean with missing data in stratified random sampling concept of Gira (2015) by simulation. The size of the population is 150,000 units with values of a study variable Y and an auxiliary variable X. When the correlation coefficient between variable Y and X has 3 levels which is 0.05, 0.75 and 0.90. Random sample is 30, 90, 300 and 600 sample units are drawn from the population. From each sample randomly the variable Y as randomly missing at 5%, 10% and 15%, respectively. The criteria used for the comparison is the mean square error. In the present study, it indicates that the proposed estimator to be more effective than those reported in Singh et al. (2015) and Thakur et al. (2014) for every cases.

Keywords :  missing data, stratified random sampling, simple random sampling, estimator of population mean,
