-This method is based on an approximation of the SIR model, which is most valid at the beginning of an epidemic.
-The method assumes that the mean of the serial distribution (sometimes called the serial interval) is known.
-The final estimate can be quite sensitive to this value, so sensitivity testing is strongly recommended.
-Users should be careful about units of time (e.g., are counts observed daily or weekly?) when implementing.
