Comment on “Estimation of COVID-19 dynamics “on a back-of-envelope”: Does the simplest SIR model provide quantitative parameters and predictions?”	2020-09-13		.txt	text/plain	1846	69	47	Thus, the dynamics of the disease, introduced in 1927 by Kermack and McKendrick [2] , is modeled by the set of differential equations: In these equations, the parameters β (the infection rate) and γ (the recovery or removal rate of infectives) are constants: β controls the transition between S and I, equation (1), while γ controls the transition between I and R, equation (3). Then, by a standard Figure 1 : The graph shows the KM approximation R(t) given in equation (7) (with fitting parameters shown in Table 1 , according to equation (11) ) and the full numerical solution of the SIR epidemiological model defined by equations (1)-(3) (with integration parameters compiled in Table 2 ), both with reasonable estimated absolute and relative rmse values are observed to adjust reported cumulative confirmed COVID-19 cases for a number of countries.	cache/cord-279112-ajdkasah.txt	txt/cord-279112-ajdkasah.txt
