Abstract

Los estimadores de calibración se han convertido en una técnica robusta y eficiente en la estimación de totales en encuestas complejas. En este trabajo se considera y aplica un importante resultado que afirma que es posible calibrar con parámetros complejos, diferentes a totales auxiliares, como la mediana, la media, la media geométrica o incluso una razón, logrando obtener estimaciones de totales con las mismas características de no tener sesgo y poseer varianza pequena. Mediante simulaciones de Monte Carlo se aplicó este resultado a poblaciones empíricas, mostrando un buen desempeno. También, se utilizó esta técnica en la Gran Encuesta Integrada de Hogares realizada por el Departamento Administrativo Nacional de Estadística, lo cual permitió concluir acerca de la eficiencia de la técnica. ******* Calibration estimators have become a robust and efficient technique when estimating totals from complex surveys. This paper considers an important result claiming that estimators can be calibrated with some other complex parameters, beyond auxiliary totals, such as medians, means, geometric means or even ratios. This way, it is possible to obtain a different class of calibration estimators inducing consistent estimates of the total population with good performance (unbiasedness and small variance). This result was applied to empirical populations and by means of Monte Carlo simulations it was shown the good performance of the technique. Also, this methodology was applies in the GEIH elaborated by DANE and it is concluded about the efficiency of this novel method.
