Permanent Random Number Sampling // Survey sampling using
permanent random numbers (PRN's). A solution to the problem of
unknown overlap between survey samples, which leads to a low
precision in estimates when the survey is repeated or combined
with other surveys. The PRN solution is to supply the U(0, 1)
random numbers to the sampling procedure, instead of having the
sampling procedure generate them. In Lindblom (2014)
doi:10.2478/jos-2014-0047, and therein cited articles, it is
shown how this is carried out and how it improves the
estimates. This package supports two common fixed-size sampling
procedures (simple random sampling and probability-
proportional-to-size sampling) and includes a function for
transforming the PRN's in order to control the sample overlap.
