Using a predictive estimation procedure, an attempt has been made to develop some estimators for the finite population variance in the presence of an auxiliary variable. Analytical and simulation studies have been undertaken for understanding the performance of the suggested estimators compared to some existing ones.
Key words: Auxiliary variable, Bias, Efficiency, Prediction approach.
Mediante el uso de un procedimiento de estimación predictivo, se desarrollan algunos estimadores de la varianza poblacional en la presencia de una variable auxiliar. Estudios analíticos y de simulación son implementados para entender el desempeño de los estimadores sugeridos en comparación con otros ya existentes.
Palabras clave: variable auxiliar, sesgo, eficiencia, enfoque de predicción.
