Summary: The author ran an ARIMA model to make a prediction about how the chikungunya virus will progress in certain Caribbean countries. The epidemic has lasted a little under two years, and there have been over 60 thousand cases in the Americas. The author has counts per week as reported by national agencies (?). She adjusts for certain errors in the data entry process, which were detected by a jump at week 72. She ran a SIR compartment model. It is a little unclear what the results are for this section. It is clear that the model is not the best one possible. She ran a multi-country SIR model for St. Martin and St. Barthelemy. This accounted for the transfer of the disease from one country to the other through people who arrive on planes. She ran an ARIMA model for forecasting and estimated the future counts per country. Dear Purvasha, I read section 4 of your paper. Your report is very well written, and I understood your methods and the problems with each one. Your exploratory data analysis is very clear and interesting. It might be interesting to draw a sketch of the compartment mode as boxes. That might make it clearer to the reader what the stages are. You might want to include a section at the beginning of your results (section 4.0 or something like that) that lists the different models used. You probably had this in an earlier methods section, but it might be helpful to introduce the results so it becomes self-contained. That way if someone is skimming your paper they can get a good idea of your results from the first paragraph in section 4. See the comments on the PDF.
