Robust bootstrap procedures for the chain-ladder method [PDF]

open access: yes, 2017
Insurers are faced with the challenge of estimating the future reserves needed to handle historic and outstanding claims that are not fully settled. A well-known and widely used technique is the chain-ladder method, which is a deterministic algorithm. To

Reserves-to-production ratio – on the reliability of estimates

open access: yesGeoresursy
At present, when estimating the state of the resource base and the general forecast for the development of oil production, ones often operate with the reservesto-production ratio, which reflects, as it is believed, a guaranteed time for involving current

Metapopulation dynamics guide marine reserve design: importance of connectivity, demographics, and stock enhancement

open access: yesEcosphere, 2016
The concepts of metapopulation persistence and source‐sink dynamics are central and often untested tenets of marine reserve networks. Effective application of these concepts to marine reserves is limited by data on demographic rates within reserves and ...
