Abstract

The purpose of this paper is to compare several sampling methods using in sampling with probability proportional size.
A sampling with probability proportional size, is divided into two, with replacement and without replacement.
In the case of sampling without replacement, we compare the sampling techniques using special estimators such as Horvitz-Thompson estimator, Das Raj estimator and Murthy estimator.
Based on the comparisons of the variance of estimators and the relative efficiency for the probability proportional size with replacement, Das Raj and Murthy estimators are more useful than other estimators in sampling with probability proportional size with replacement.
Especially, the method of Murthy has a high efficiency than others.
