Método de exploración secuencial cuasi equilibrado en muestreo en poblaciones finitas [PDF]
En este trabajo se propone un procedimiento de muestreo de tipo secuencial que proporciona probabilidades de inclusión de primer orden proporcionales al tamaño, sobre bloques de la población, siendo las de segundo orden nulas para pares de elementos ...

INDIRECT SAMPLING in the CONTEXT of DUAL FRAME SURVEYS [PDF]
Under-coverage is one of the most common problems of sampling frames. To reduce the impact of coverage error on survey estimates several frames can be combined in order to achieve a complete (or nearly complete) coverage of the target population ...

Finite sample properties of multiple imputation estimators
Finite sample properties of multiple imputation estimators under the linear regression model are studied. The exact bias of the multiple imputation variance estimator is presented. A method of reducing the bias is presented and simulation is used to make

On the two-phase framework for joint model and design-based inference
We establish a mathematical framework that formally validates the two-phase ``super-population viewpoint'' proposed by Hartley and Sielken [Biometrics 31 (1975) 411--422] by defining a product probability space which includes both the design space and ...
