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, ...

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 ...

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 ...

The specific monitoring design (the choice of location and timing of sample collection) that best meets project objectives will depend on the type and scale of the project and the degree to which ...

Today's analog system designers face many design challenges. Not only do designers need to select the proper integrated-circuit components, but they also must accurately predict the interactions of ...

The PROC SURVEYSELECT statement invokes the procedure and optionally identifies input and output data sets. If you do not name a DATA= input data set, the procedure selects the sample from the most ...
