Small-area estimation with state-space models subject to benchmark constraints (2006)

Pfeffermann, Danny, Tiller, Richard

This article shows how to benchmark small area estimators, produced by fitting separate state-space models within the areas, to aggregates of the survey direct estimators within a group of areas....

Multi-level modelling under informative sampling (2006)

Pfeffermann, Danny, Da Silva Moura, Fernando Antonio, Do Nascimento Silva, Pedro Luis

We consider a model-dependent approach for multi-level modelling that accounts for informative probability sampling of first- and lower-level population units. The proposed approach consists of first...

Bootstrap approximation to prediction MSE for state-space models with estimated parameters (2005)

Pfeffermann, Danny, Tiller, Richard

We propose simple parametric and nonparametric bootstrap methods for estimating the prediction mean square error (PMSE) of state vector predictors that use estimated model parameters. As is well...

Small Area Estimation under a Two Part Random Effects Model with Application to Estimation of Literacy in Developing Countries (2005)

Pfeffermann, Danny, Terryn, Bénédicte, Moura, Fernando

The UNESCO Institute for Statistics has initiated a programme to collect data on the level of literacy of adults in developing countries. This will involve conducting small-scale surveys in a few...

Small area estimation under varying area boundaries using the synthetic estimator (2005)

Moura, Fernando, Clarke, Philip, Pfeffermann, Danny

This paper investigates the use of hierarchical models for small area estimation with varying area boundaries, employing the synthetic estimator. The paper shows how area estimates and corresponding...

State-Space Modeling with Correlated Measurements with Application to Small Area Estimation Under Benchmark Constraints (2003)

Pfeffermann, Danny, Tiller, Richard

The problem of Small Area Estimation is how to produce reliable estimates of area (domain) characteristics, when the sizes within the areas are too small to warrant the use of traditional direct...

Small Area Estimation Under Informative Sampling (2003)

Pfeffermann, Danny, Sverchkov, Michail

This article proposes two approaches for small area estimation under informative sampling. The semi-parametric approach makes no assumptions regarding the relationship between the area selection...

Small area estimation: new developments and directions (2002)

Pfeffermann, Danny

The purpose of this paper is to provide a critical review of the main advances in small area estimation (SAE) methods in recent years. We also discuss some of the earlier developments, which serve as...

The estimation of gross flows in the presence of measurement error using auxiliary variables (1998)

Pfeffermann, Danny, Skinner, Chris, Humphreys, Keith

Classification error can lead to substantial biases in the estimation of gross flows from longitudinal data. We propose a method to adjust flow estimates for bias, based on fitting separate...

Poststratification using regression estimators when information on strata means and sizes is missing (1991)

PFEFFERMANN, DANNY, KRIEGER, ABBA M.

Poststratification is often used to increase the precision of survey estimators. When applied to regression estimators, it assumes that the regression relationships in the various strata are...
