The method of systematic random sampling (METHOD=SYS) selects units at a fixed interval throughout the sampling frame or stratum after a random start. PROC SURVEYSELECT chooses the first unit randomly ...

In this paper, a slight modification of linear systematic sampling procedure that maintains the simplicity of selection is proposed. The procedure depends on the remainder only and can be used for ...

If you specify the option METHOD=PPS_SYS, PROC SURVEYSELECT selects units by systematic random sampling with probability proportional to size. Systematic sampling selects units at a fixed interval ...

Sampling is a type of scientific surveying which can save time and money and give information on the population of animals and plants. There are many different types of sampling; the most useful type ...
