haha i can save you some time. there are two models. the first is hypersimplistic, reciprocal of an decaying exponential with four parameters and zero inflection points (although there's one visible in the data so far)... it does not even come close to addressing your questions. the second model at least accounts for decay - gee - but is still essentially two terms with three parameters- the result is two competing decay terms. This is, essentially, a trivial joke. it has no delay parameters for incubation, etc. I've only skimmed the article, but I can't find an actual attribution of these numbers to the model (the model itself is from a journal). It seriously appears like an editor said, "Let's get some scary-mathy-lookin stuff up there on Ebola). if it bleeds...
