This paper considers the problem of estimating the population total in two-stage cluster sampling when cluster sizes are unknown, making use of a population model arising basically from a variance component model. The problem can be considered as one of predicting the unobserved part Z of the...

Like other data quality dimensions, the concept of accuracy is often adopted to characterise a particular data set. However, its common specification basically refers to statistical properties of estimators, which can hardly be proved by means of a single survey at hand. This ambiguity can be...

Statistical procedures for missing data have improved significantly in the last years. This study put the missing data in context and makes a revision of the recent literature for the case that the missing data problem is ignorable. In an application, based in real data of a psychographic...
