Like the video camera, most sampling schemes are periodic; that is, they have a characteristic sampling frequency in time or in space.
The proportionator adjusts the sampling scheme to select samples that are likely to provide estimates that have a smaller difference.
Usually the jackknife is easier to apply to complex sampling schemes than the bootstrap.
Each box indicates how many different sets of choices there are, in a particular sampling scheme.
Results of our analyses were unchanged after adjusting for the weighted sampling scheme.
Basic spatial sampling schemes include random, clustered and systematic.
A sampling scheme must be proposed (see Chapter 17).
Gaston et al. note that because of this relationship, the intensiveness of a sampling scheme cannot be traded off for extensiveness.
Results Table 1 shows the characteristics of the sample, unadjusted for the weighted sampling scheme.
Sample households are selected by a multistage stratified statistical sampling scheme.
