We present a simple but universal technique for the construction of π PS sampling designs. A tool that is used in the construction consists of playing a game in which objects are removed from N boxes, ...

In this paper we consider a family of sampling designs for which increasing first-order inclusion probabilities imply, in a specific sense, increasing conditional inclusion probabilities. It is proved ...

Outcome-dependent sampling designs are strategic methodologies in longitudinal research that prioritise the selection of study subjects based on observed outcomes. Rather than relying on random ...
