New methods to handle nonresponse in surveys

Hasler, Caren ; Tillé, Yves (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

This document focuses on nonresponse in sample surveys. Mainly, methods to handle nonresponse in complex surveys are proposed. The first chapter of this document introduces concepts and notation of survey sampling and nonresponse. The second chapter proposes an algorithm for stratified balanced sampling for populations with large numbers of strata. The third chapter of this document presents a...

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...
