Part A - SIR model for the spread of disease Overview. This part of the assignment uses a mix of theory and data to estimate the contact number c=b/k of an epidemic and hence to estimate the infection-spreading parameter b. The point is that once you know the value of b for a certain disease and pop...
##### Moving Walkway
