In equal probability sampling, each unit in the sampling frame, or in a stratum, has the same probability of being selected for the sample. PROC SURVEYSELECT provides the following methods that select ...
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 ...
An example of this is an investigation into whether the growth of seaweed depends upon the distance it is found on the seashore from the tide. We would use systematic sampling as we are looking to ...
In particular, two-dimensional extensions of known approximate variance estimators used in linear systematic sampling are introduced. These almost new variance estimators have the advantage of taking ...
PPS Systematic Sampling 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 ...
