areppim: information, pure and simple
How good does the logistic S-curve fit the deaths data for the countries of which we have been tracking the number of infections? To get an insight into it, we have computed the curve values for the data available on 22 May 2020. The results show that the goodness of fit is at least as good for the deaths as it is for the infections.
We would also like to ascertain how accurate are the S-curve predictions. The curves show that in most of the selected countries the number of deaths are moving close to their upper limit. That is good news — but is it reliable? The future will tell... We never bragged about the clairvoyant power of the logistic S-curve or any other mathematical tool for that matter. But we maintain that it helps to get a clearer view of what is going on.
