UNA CLASE DE ESTIMADORES BASADOS EN UNA RAZÓN: MUESTREO SIMPLE ALEATORIO Y MUESTREO POR CONJUNTOS ORDENADOS

Abstract

A class of estimators is determined. It contains important families of ratio estimators. The belonging to it is characterized by means of a parametric vector. It allows identifying that more than a dozen of estimators are particular cases. Their behavior when ranked set sampling is used is established by fixing the gains in accuracy of them. Numerical experiments establish which is the performance of them in four applications and by generating normal, exponential and uniform populations
