However, these results are purely probabilistic, and the geometric approach itself has not been fully exploited for statistical inference. We outline a method for parametric estimation of the limit set shape, which includes a useful non-\/semi-parametric estimate as a pre-processing step. More fundamentally, our approach provides a new class of asymptotically motivated statistical models for the tails of multivariate distributions, and such models can accommodate any combination of simultaneous or non-simultaneous extremes through appropriate parametric forms for the limit set shape. Extrapolation further into the tail of the distribution is possible via simulation from the fitted model. A simulation study confirms that our methodology is very competitive with existing approaches and can successfully allow estimation of small probabilities in regions where other methods struggle. We apply the methodology to two environmental datasets, with diagnostics demonstrating a good fit.<\/jats:p>","DOI":"10.1093\/jrsssb\/qkae030","type":"journal-article","created":{"date-parts":[[2024,3,28]],"date-time":"2024-03-28T20:21:29Z","timestamp":1711657289000},"page":"1243-1265","source":"Crossref","is-referenced-by-count":12,"title":["Statistical
