Estimation de la précision d’évolutions dans les enquêtes répétées, application à l’enquête suisse sur la valeur ajoutée

Qualité, Lionel ; Tillé, Yves

In: Techniques d’enquête, 2008, vol. 34, no. 2, p. 193-201

Nous proposons une méthode pour estimer la variance des estimateurs des évolutions qui prend en compte toutes les composantes de ceux-ci : le plan de sondage, le traitement des non-réponses, le traitement des grosses entreprises, la corrélation de la non-réponse d’une vague à l’autre, l’effet dû à l’utilisation d’un panel, la robustification et le calage au moyen d’un...

Variance estimation of changes in repeated surveys and its application to the Swiss survey of value added

Qualité, Lionel ; Tillé, Yves

In: Survey Methodology, 2008, vol. 34, no. 2, p. 173-181

We propose a method for estimating the variance of estimators of changes over time, a method that takes account of all the components of these estimators: the sampling design, treatment of non-response, treatment of large companies, correlation of non- response from one wave to another, the effect of using a panel, robustification, and calibration using a ratio estimator. This method, which...

General framework for the rotation of units in repeated survey sampling

Nedyalkova, Desislava ; Tillé, Yves ; Qualité, Lionel

In: Statistica Neerlandica, 2009, vol. 63, no. 3, p. 269-293

Coordination of probabilistic samples is a challenging theoretical problem faced by statistical institutes. One of their aims is to obtain good estimates for each wave while spreading the response burden across the entire population. There is a collection of existing solutions that try to attend to these needs. These solutions, which were developed independently, are integrated in a general...

Unequal probability sampling and repeated surveys

Qualité, Lionel ; Tillé, Yves (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2009 ; Th. 2091.

This document is divided into two parts. The first part revolves around the properties of some unequal probability survey sampling designs, and the second part deals with repeated surveys. While the topics developed in these two parts appear to be largely different, they are in fact related. The first part is devoted to the study of properties of two sampling designs with fixed size. In a first...
