  1. AIC values obtained with each mobility model, for the 2010 Haiti cholera epidemic, assuming that the overall probability of mobility (α) is not given by CDRs, but fitted. The indicated models are: impedance model (IM), gravity model (GM), and radiation model (RM). Results are presented for the two spatial definitions. ∆ AIC corresponds to the variation from the optimal AIC value derived from the CDRs
