This manuscript is dedicated to the use of auxiliary information in survey sampling and nonresponse. We are interested in the integration of auxiliary variables in sampling methods and in the treatment of nonresponse to improve the efficiency and the precision of surveys. We also deal with the calculation of the precision of estimators. Indeed, variances rapidly become difficult to calculate when...

Measuring inequality in finite population sampling

Langel, Matti ; Tillé, Yves (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2012 ; 2252.

This document focuses on the estimation of inequality measures for complex survey data. The proposed methodology takes into account both the complexity of these generally non-linear functions of interest and the complexity of the sampling strategy. The first chapter is dedicated to the presentation and definition of the main concepts used in both inequality and survey sampling theory. In the...
