Modeling lower-truncated and right-censored insurance claims with an extension of the MBBEFD class

S Gatti, MV Wüthrich - arXiv preprint arXiv:2310.11471, 2023 - arxiv.org
In general insurance, claims are often lower-truncated and right-censored because
insurance contracts may involve deductibles and maximal covers. Most classical statistical …
