| Overview | This model takes a historical approach in demonstrating that environmental signatures can predict cholera epidemics. Satellite derived datasets were used to model the relationship between these related environmental factors and cholera dynamics in Kolkata and Matlab, Bangladesh. |

| Question | Which environmental factors are associated with cholera epidemics in the northern Bay of Bengal? |

| General notes | "Because the three environmental datasets show a strong seasonal pattern, anomalies were computed to remove the effect of the annual cycle, which can result in spurious relationships between cotrending variables." |

| Verification & validation notes | Validation: to evaluate the models computed on the whole dataset, cross-validations predictions were also made from the model by predicting cholera cases for each year using the final model structure, i.e., with only significant parameters, but estimating coefficients on the data set without data for the year under consideration.The model was verified. |
