Residual plots of the model fitted to the Compliance poaching data of Super-area 8+ reported in Brandão and Butterworth (2021) are shown for the case when all data are used in the analysis, as well as for the sensitivity when the largest confiscation records from 2020 are omitted from the analysis. Results are also shown for a further sensitivity in which records with large residuals for the base case model (i.e. the model fitted to all data) are removed from the analysis.
