A national survey designed for estimating a specific population quantity is sometimes used for estimation of this quantity also for a small area, such as a province. Budget constraints do not allow a greater sample size ...
On the performance of small-area estimators: fixed vs. random area parameters
(Institut d'Estadística de Catalunya, 2009)
Article.

Most methods for small-area estimation are based on composite estimators derived from designor model-based methods. A composite estimator is a linear combination of a direct and an indirect estimator with weights that ...
An empirical evaluation of five small area estimators

This paper compares five small area estimators. We use Monte Carlo simulation in the context of both artificial and real populations. In addition to the direct and indirect estimators, we consider the optimal composite ...
Improving both domain and total area estimation by composition
(Institut d'Estadística de Catalunya, 2004)
Article.
Accés obert
Article.
Accés obert
In this article we propose small area estimators for both the small and large area parameters. When the objective is to estimate parameters at both levels, optimality is achieved by a sample design that combines fixed and ...
