You guess, just like everyone else. I think the difference is that my model will be an equation that takes individual country statistics to make predictions instead of global statistics. You can expect that Iran, for example, will have a higher infection rate, higher death rate, and lower recovery rate because of the nature of their society - no social distancing, and high rate of smoking. The UK and France will be higher infection rate, higher death rate, and lower recovery rate because certain segments of their population are not required to comply with the stay-at-home orders (the Muslim zones refused to comply and police were ordered not to force them)
Anyway, I'm still working on importing 2 months worth of data, then I'll start working on the historical graphing and country comparison graphs. After that, who knows....maybe I'll look for a way to determine peak infection....it all depends on how reliable the data is....and how much I have to guess.
