Gómez-Corral, AntonioLópez-García, M.2023-06-192023-06-192013-040307-904X10.1016/j.apm.2012.10.035https://hdl.handle.net/20.500.14352/33290In this paper, we present a host-parasitoid model with correlated events. We apply a block-structured state-dependent (BSDE) approach that provides a methodological tool to model state-dependent Markovian transitions operating in the presence of phases. A particularly appealing feature of the resulting BSDE host-parasitoid model is that it allows us to deal with non-exponential distributional assumptions on a host birth, a parasitoid death, and parasitism, but keeping the dimensionality of the underlying block-structured Markov chain tractable. Numerical examples are presented to illustrate the effects of the correlation structure on the expected extinction times and the extinction probabilities.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0307904X12006403http://www.sciencedirect.com/restricted access519.2BSDE approachExtinctionHost-parasitoid modelMarkov chain modelMarkov-modulated eventsEstadística matemática (Matemáticas)1209 Estadística
