The aim of this paper is to make imputations of earnings to observations with missing earnings in the Encuesta Nacional de Ocupaciones y Empleo (ENOE). We present imputations by two methods and also a correction of estimations by reweighting observations with reported earnings. Then, we analyze...

La eficiencia técnica y asignativa son análisis relativos, empleados en procesos productivos para conocer el máximo nivel producido y cantidad óptima utilizada de insumos acorde con sus precios. El presente estudio maneja datos microeconómicos de caficultores pequeños, medianos y grandes...

The estimation of the sample size is a crucial part of the planning process of a survey and it can be accomplished in different ways, some of them require information not available or that may be obtained with a substantial cost. The estimation of the sample size can be done by using the design...

In the estimation of proportions using simple random sampling, the maximum value of the variance can be used to compute the sample size when there is no information of the variable of interest. We extend this result to the estimation of proportions under two-stage cluster sampling with equal...

In stratified sampling there are designs with one unit selected per stratum or when one is willing to make estimations on unplanned domains with one unit in some strata. In these cases the variance is generally estimated by the collapsed strata method, which requires identification of the strata...
