itsdm

Collection of R functions to do purely presence-only species distribution modeling with isolation forest (iForest) and its variations such as Extended isolation forest and SCiForest. See the details of these methods in references: Liu, F.T., Ting, K.M. and Zhou, Z.H. (2008) doi:10.1109/ICDM.2008.17, Hariri, S., Kind, M.C. and Brunner, R.J.

(2014) doi:10.1007/s10115-013-0679-x. itsdm also provides functions to diagnose variable response, analyze variable importance, draw spatial dependence of variables and examine variable contribution. As utilities, the package includes a few functions to download bioclimatic variables including 'WorldClim' version 2.0 (see Fick, S.E. and Hijmans, R.J. (2017) doi:10.1002/joc.5086) and 'CMCC-BioClimInd' (see Noce, S., Caporaso, L. and Santini, M. (2020) doi:10.1038/s41597-020-00726-5).
