Comment on Dehning et al (Science, 15 May 2020, eabb9789: Inferring
change points in the spread of COVID-19 reveals the effectiveness of
interventions)
Abstract
Dehning et al. (Science, 15 May 2020: eabb9789) report change points in
the growth rate of SARS-CoV-2 infections that promptly respond to
non-pharmaceutical interventions (NPIs). We challenge their findings on
methodological and empirical grounds.
