This Ph.D. thesis concentrates on two important subjects in survey sampling theory. One is the problem of the foundation for statistical inference in finite population sampling, and the other is the problem of coordination of samples over time. The thesis is based on four articles. Three of them are already published and the last one is submitted for publication. First, we show that the...

Handling auxiliary variables in survey sampling and nonresponse

Vallée, Audrey-Anne ; Tillé, Yves (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

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...
