COVID-19 reproduction number data calculated from the datasets of COVID-19 infection in a few countries

Raw data have been collected for the USA, Denmark, China, Italy , Germany, France, Singapore (from 22 January, 2020 to 26 April, 2020) and India (upto 2 May, 2020) and produced in log-log scale for power law fitting. The fitted data for different power law exponents are also submitted here. The new number of observed cases per day in these countries has been extracted from the raw data for application of Farr's law. The fitted Gaussian curve is also submitted here. The temporal dynamics of the reproduction number R0 is calculated from these data using Farr's law and IDEA model and compared for three different countries-the USA, Italy and India. The details can be seen in https://www.medrxiv.org/content/10.1101/2020.05.04.20090233v1. The detailed paper will be submitted in peer reviewed journal Epidemics . The raw data have been collected from https://github.com/CSSEGISandData/COVID-19, https://coronavirus.jhu.edu/map.html and https://www.mohfw.gov.in/.
