USE OF LINEAR AND POWER TRANSFORMATIONS FOR ESTIMATING THE POPULATION MEAN IN TWO-OCCASION SUCCESSIVE SAMPLING

Surya K. Pal, Housila P. Singh

Resumen


The paper advocates the problem of estimating population mean on the current (second) occasion using auxiliary information in
successive sampling over two-occasions. A class of estimators based on transformed auxiliary variable is derived. The bias and
mean square error of the proposed estimator have been obtained. The suggested estimator has been compared with simple mean
estimator when there is no matching and the optimum estimator, which is a combination of the means of the matched and unmatched
portion of the sample at the second occasion. Optimum replacement policy and the efficiency of the suggested
estimator have been discussed. Numerical Illustration is given in support of the present study.
KEYWORDS: Auxiliary variable, study variable, successive sampling, mean square error.
