    Snippet: where in the left-hand side we have explicitly denoted the dependence of the solution of the RGM on the four parameters, namely r, α, K, and t c . In Sec. 4 we show results of the application of the Richard growth curve (3) to the mortality data of COVID-19 for several countries. We note, however, that the RGM is not reliable in situations where the epidemics is in such an early stage that the available data is well below the estimated inflectio.....
    Document: where in the left-hand side we have explicitly denoted the dependence of the solution of the RGM on the four parameters, namely r, α, K, and t c . In Sec. 4 we show results of the application of the Richard growth curve (3) to the mortality data of COVID-19 for several countries. We note, however, that the RGM is not reliable in situations where the epidemics is in such an early stage that the available data is well below the estimated inflection point t c , i.e., when the epidemic is still in the so-called exponential growth regime [13] . In this case, it is preferable to use the socalled generalized growth model [13, 22] , which is defined by the following
