  Estimation of Population Mean Under SRSWOR Using Imputation Technique

  By Prabhakar Mishra, Poonam Singh, Rajesh Singh

  Abstract: This research work suggests four log-type imputation methods using auxiliary information for missing observations in a data set. These methods consist of corresponding point estimator for estimating population mean under simple random sampling without replacement. Bias and mean square error expressions are derived up-to first order of approximation. Percent relative efficiency of suggested estimators is compared with the existing estimators using four population real data sets. And it is empirically …
