Peter M. Aronow and Cyrus Samii, Survey Methodology, volume 39, number 1 (June 2013). Exact primary byline and research article on the publisher Statistics Canada site. Section 2 https://www150.statcan.gc.ca/n1/pub/12-001-x/2013001/article/11831/section2-eng.htm defines individual and pairwise inclusion positivity; section 2.1 gives the Horvitz-Thompson variance and unbiased pair-expansion variance estimator; section 2.2 and Proposition 1 identify missing cross-products when pairwise inclusion probabilities vanish. The original paper affiliations are Yale Department of Political Science and NYU Department of Politics. Publication year 2013 is distinct from the archived HTML modification date 2017-09-20.

Section3 https://www150.statcan.gc.ca/n1/pub/12-001-x/2013001/article/11831/section3-eng.htm gives the Young-inequality correction for missing pair products: Proposition2 establishes conservativeness in expected value, and Section3.2 specializes both exponents to2. This is an expectation bound, not a guarantee that each realized variance estimate exceeds the true variance or that a normal confidence interval has its advertised coverage.
