Cure models: from mixture to matrix distributions

Martin Bladt, Jorge Yslas

Cure rate models address survival data in which a proportion of individuals will never experience the event of interest. Existing parametric approaches are predominantly based on f…

Assessing continuous common-shock risk through matrix distributions

Martin Bladt, Oscar Peralta, Jorge Yslas

We introduce a class of continuous-time bivariate phase-type distributions for modeling dependencies from common shocks. The construction uses continuous-time Markov processes that…

Bivariate phase-type distributions for experience rating in disability insurance

Christian Furrer, Jacob Juhl Sørensen, Jorge Yslas

In this paper, we consider the problem of experience rating within the classic Markov chain life insurance framework. We begin by establishing a link between mixed Poisson distribu…

Phase-type frailty models: A flexible approach to modeling unobserved heterogeneity in survival analysis

Jorge Yslas

Frailty models are essential tools in survival analysis for addressing unobserved heterogeneity and random effects in the data. These models incorporate a random effect, the frailt…
