3.2. The rate of new appearances for the SIS model. If you answered the questions above correctly, then you can observe that, if we call x = I(t) and y = (t) I(t) , then y = mx + b and y is given by a straight line!! Question: what is the slope of this line? Question: what do you think y represents? Can we estimate y from Hospital numbers? 3.3. The rate of new appearances for the asymptomatic SIS model. Now, write down the equation for y = (t) in terms of x = I(t) for the asymptomatic I(t) SIS model. Is it a straight line?
