Estimation for the Birnbaum-Saunders (BS) regression model has been discussed by various authors when data are either complete or subject to Type-I or random censoring. But, this problem has not been considered for the case of interval censoring. In this article, we discuss the estimation of a...

In order to model random population dynamics with cycles in ecosystems, we construct a diffusion process with random jumps from the boundary. The evolution of this new process is investigated. It is shown that the behavior of the whole process is uniquely determined by its first hitting time and...

The uncontrolled surplus of an insurance company is a classical risk model. Now the risk model includes three features, namely debit interest, short-term and long-term invested interest, and linear dividend barrier. In this paper, the PDMP method and martingales are used for solvency studies in...
