Calculating multivariate ruin probabilities via Gaver–Stehfest inversion technique

M Usábel - Insurance: Mathematics and Economics, 1999 - Elsevier
Multivariate characteristics of risk processes are of high interest to academic actuaries. In
such models, the probability of ruin is obtained not only by considering initial reserves u but …

Bounds for ruin probabilities in the presence of large claims and their comparison

V Kalashnikov - North American Actuarial Journal, 1999 - Taylor & Francis
Upper and lower bounds of ruin probabilities for the S. Andersen model with large claims

[HTML][HTML] Burr distribution as an actuarial risk model and the computation of some of its actuarial quantities related to the probability of ruin

J Das, DC Nath - Journal of mathematical finance, 2016 - scirp.org
In this paper, we have used an algorithm to fit the Burr XII distribution to a set of insurance
data. As it is well known, the probability of ultimate ruin is obtained as a solution to an …

Ultimate ruin probabilities for generalized Gamma-convolutions claim sizes
