THE “FLU SEASONS” AND THE MISSING DATA: A MATCHED-PAIR ANALYSIS FOR THE PANDEMIC SEASON 2019_2020

Abstract

The unit cell from the McNemar’s 2x2 Table denotes the week with col (1, 2) and the Public Health Region with Row (1, 2). We calculate the standard normal statistic (z) for A(H1), A(H3), Influenza B. Each one categorical unit is in fact a pair of matched-pair data within its own partial table.  The Cochran-Mantel-Haenszel Test collapses these partial tables to summate these 2n observations in a 2x2 x n contingency table to yield the marginal counts of the McNemar’s test. The open data for Europe/Asia began this SARS-CoV2 pandemic, from week 3 to week 14, with the normal statistic (z) entering into an identical collapse mode.  These all assumed the same “V” curve as the general collapse pattern and they rippled together without overlapping. During this period China applied mandatory lockdown and they mandated masks. We should strive to be more evidence-based so that we can convince more of the general public to accept the public health measures to survive.
