“…We use central tendency measures to assist in interpreting the results obtained with a second-order difference plot. Central tendency measures play an important role in understanding the typical values of a time series and how they change over time ( Cohen et al., 1996 ; Belfort et al., 2019 ; dos Santos et al., 2015 ). Represented by a second-order difference plot, this method allows to obtain a comprehensive understanding of a time series allowing us to infer the behavior of the virus spreading and uncover valuable pieces of information from time-dependent data.…”
