text:
In survey methodology, probability-proportional-to-size (pps) sampling is a sampling process where each element of the population has some (independent) chance p i to be selected to the sample when performing one draw. This p i is proportional to some known quantity x i so that p i = x i ∑ i = 1 N x i . One of the cases this occurs in, as developed by Hanson and Hurwitz in 1943, is when we have several clusters of units, each with a different number of units, then each cluster can be selected wi
