On the inclusion probabilities in some unequal probability sampling plans without replacement
Comparison results are obtained for the inclusion probabilities in some unequal probability sampling plans without replacement. For either successive sampling or Hájek’s rejective sampling, the larger the sample size, the more uniform the inclusion probabilities in the sense of majorization. In particular, the inclusion probabilities are more uniform than the drawing probabilities. For the same...
متن کاملSize constrained unequal probability sampling with a non-integer sum of inclusion probabilities
More than 50 methods have been developed to draw unequal probability samples with fixed sample size. All these methods require the sum of the inclusion probabilities to be an integer number. There are cases, however, where the sum of desired inclusion probabilities is not an integer. Then, classical algorithms for drawing samples cannot be directly applied. We present two methods to overcome th...
متن کاملAn Empirical Study of some Unequal Probability Sampling Estimators
An empirical study has been carried out to decide about the performance of various estimators used in unequal probability sampling without replacement and a sample of size 2. The Hansen–Hurwitz estimator and simple random sampling method has also been compared in this study. Some suggestions have been given at the end.
متن کاملOn Successive Sampling and Fixed Inclusion Probabilities
In the method of successive sampling, a sample of n distinct units is drawn from a population of N units one at a time. Each unit i is drawn with a fixed selection probability pi and any repeated units are ignored. When the pi are proportional to a given size measure, this is called probability proportional to size without replacement (PPSWOR). The first order inclusion probabilities πi of each...
متن کاملآنتروپی طرح های نمونه گیری با احتمال نابرابر
the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
