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 ...

Cohort sampling designs are proposed which one would intuitively expect to be more efficient than nested case-control sampling. Two of these designs start with a nested case-control sample and ...

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 ...

Whenever you design a sample for a CX project, you lay an indispensable foundation for creating reliable and functional insights for your organization. For too many, improving customer experience ...

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 ...
