Analysis of the prediction of the 2021 time-evolution of the Covid-19 pandemic in Italy using a Planck’s distribution
In a previous paper, we studied the time-evolution of the Covid-19 pandemic in Italy during the first wave of 2020 using a number of distribution laws. We concluded that the best distribution law to predict th...
