A study of optimal sampling schemes

Abstract

This thesis comprises a research of optimal sampling designs. Firstly, I insert the theory of the standard sampling methods under finite population and I find the estimators of quantities of the population of these methods. Then, I insert the idea of the superpopulation approach. Optimal sampling methods under autocorrelated finite populations are presented in chapter 4. I analyse there, four optimal sampling designs. I present finally a short comparison of these optimal sampling schemes.
