Informative sampling refers to a sampling design for which the sample selection probabilities depend on the values of … response units under informative sampling and nonignorable nonresponse. This is the most general situation in surveys and other … combinations of sampling informativeness and response mechanisms can be considered as special cases. Furthermore, based on the …

In this paper, we combine two methodologies used in the model-based survey sampling, namely the prediction of the … finite population total, named T, under informative sampling and full response, see Sverchkov and Pfeffermann (2004), and the … prediction of T with a noninformative sampling design and the nonignorable nonresponse mechanism, see Eideh (2012). The former …

Zusammenfassung Gerade bei Umfragen mit sog. sensitiven Variablen, wie etwa dem Einkommen, ist bekannt, daß z. B. die Bezieher sehr hoher Einkommen eher zur Verweigerung der Beantwortung von Einkommensfragen neigen als andere. Einfaches Vernachlässigen der unvollständigen Datensätze für die...

Good estimates of HIV prevalence are important for policy makers in order to plan control programs and interventions. Although population-based surveys are now considered the "gold standard" to monitor the HIV epidemic, they are usually plagued by problems of nonignorable nonresponse. This paper...

We propose Bayesian methods with five types of priors to estimate cell probabilities in an incomplete multi-way contingency table under nonignorable nonresponse. In this situation, the maximum likelihood (ML) estimates often fall in the boundary solution, causing the ML estimates to become...
