Includes datasets with the detection data of five alien reptiles in 34 survey sites, and a dataset with the features of each site. Please, refer to the metadata document in the 'Species and site data' for further details. Code A1: Annotated NIMBLE code for running the Bayesian regularised models for estimating the abundances and probabilities of detection of alien reptiles in Christmas Island. For convenience, these are the scientific and common names of the five alien reptile species: Common house gecko (Hemidactylus frenatus) Stump-toed gecko (Gehyra mutilata) Grass skink (Lygosoma bowringii) Flowerpot snake (Indotyphlops braminus) Wolf snake (Lycodon capucinus)
