UNBIASED RATIO AND PRODUCT TYPE ESTIMATORS IN PPSWR
S. Sampath (India) and R. Malathi (India)
|
Abstract: In this paper, two unbiased estimators for the population
total which use the knowledge of auxiliary information are developed under
Probability Proportional to Size Sampling with Replacement and variances of the
developed estimators are also obtained explicitly. The theory developed in this
paper is supported by empirical illustrations and computer based simulation. |
Keywords and phrases: unbiased estimators, probability proportional sampling, ratio,
regression estimation, variance, bias. |
