High nonresponse rates have become a rule in survey sampling. In panel surveys there occur additional sample losses due … to panel attrition, which are thought to worsen the bias resulting from initial nonresponse. However, under certain … conditions an initial wave nonresponse bias may vanish in later panel waves. We study such a "Fade away" of an initial …

We develop a new Bayesian estimator that is able to deal with multivariate panel data structure in the presence of … spatial correlation. The analysis of panel data introduced here allows us to analyze not only the fixed effect but also the …
