 The retained model is in bold. AA stands for Ae. albopictus (abundance), AE for Ae. aegypti (presence/absence), n for sample size (three outliers were removed) and k for the number of parameters. Only the five best models are shown but all possible models (i.e., with all variable numbers and combinations) were built.
