Yes, well, now... In reply to the question, " Suggest how you would resolve the staging difficulties inherent in the SIR model'" you have written, quote,
"Do it on Python. "
Like capturing all ideas into one ODE.What "staging difficulties" do they have in mind? SIR is a clearly defined model - as such it has no "difficulties". One uses or designs a different model if SIR isn't right. Or am again I not catching up with the creative use of English grammar inherent in scientific speech?
