Covid 19 and A Wavelet Analysis of the Total Deaths per Month in Brazil since 2015
Abstract
We investigate the historical series of the total number of deaths per month in Brazil since 2015 using the wavelet transform, in order to assess whether the COVID-19 pandemic caused any change point in that series. Our wavelet analysis shows that the series has a change point in the variance. However, it occurred long before the pandemic began.
