The “Flu Seasons” and the Missing Data: A Matched-Pair Analysis Northern and Southern Hemispheres 2013-2014 and Hong Kong, China 2004-2009

Abstract

Background: The matched-pair analysis does not compare between viruses the magnitude of positivity rates or the number of positive specimens from different regions. Each virus among n is match-paired with itself in the two responses of its own partial table. The Cochran-Mantel-Haenszel Test collapses all these partial tables with all the 2n observations in a 2x2 x n contingency table to yield the marginal counts of the McNemar's Test. We want to know if, when and how it holds for our live presentations of the Laboratories' real-time observations.
