Inclusion probability
From AWF-Wiki
In probabilistic sampling each element of the population must have a non-zero probability to be included in a sample, otherwise unbiased estimation is not possible. The inclusion probability \({\pi}_i\,\) refers to the chance that the \(i^{th}\) population element becomes part of a sample. The inclusion probability should be distinguished from the selection probability \(p(s)\) of a sample that is the probability that a certain unordered set of elements is selected as sample.
