TL;DR: In this article, a simple first-order nonnegative bilinear time-series model is studied and conditions under which the model is stationary are given, and the probability density function of the stationary distribution is found.
Abstract: We study a simple first-order nonnegative bilinear time-series model and give conditions under which the model is stationary. The probability density function of the stationary distribution (when it exists) is found. We also discuss the tail behaviour of the stationary distribution and calculate the probability density function by a numerical method. Simulation is used to check the calculation.

TL;DR: This paper treats a k-unit system with s-dependent failure rate and general repair time distribution, and ak-unit cold-standby system with Erlang failure time distribution and general Repair time distribution.
Abstract: This paper considers k-unit systems with repair. Reliability and availability integral equations are set up using renewal theory. This paper treats a k-unit system with s-dependent failure rate and general repair time distribution, and a k-unit cold-standby system with Erlang failure time distribution and general repair time distribution.

TL;DR: In this article, consistent variance estimators for certain stochastic processes are suggested using the fact that (weak or strong) invariance principles may be available, and convergence rates are also derived, the latter being essentially determined by the approximation rates in the corresponding invariance principle.
Abstract: Consistent variance estimators for certain stochastic processes are suggested using the fact that (weak or strong) invariance principles may be available. Convergence rates are also derived, the latter being essentially determined by the approximation rates in the corresponding invariance principles. As an application, a change point test in a simple AMOC renewal model is briefly discussed, where variance estimators possessing good enough convergence rates are required.

TL;DR: For a single renewal process or several renewal processes operating in parallel, this paper gave an asymptotic expansion that contains in successive terms a Poisson point approximation, a generalization of the Altschul-Gish correction, and a correction term beyond that.
Abstract: Consider a renewal process. The renewal events partition the process into i.i.d. renewal cycles. Assume that on each cycle, a rare event called 'success’ can occur. Such successes lend themselves naturally to approximation by Poisson point processes. If each success occurs after a random delay, however, Poisson convergence may be relatively slow, because each success corresponds to a time interval, not a point. In 1996, Altschul and Gish proposed a finite-size correction to a particular approximation by a Poisson point process. Their correction is now used routinely (about once a second) when computers compare biological sequences, although it lacks a mathematical foundation. This paper generalizes their correction. For a single renewal process or several renewal processes operating in parallel, this paper gives an asymptotic expansion that contains in successive terms a Poisson point approximation, a generalization of the Altschul-Gish correction, and a correction term beyond that.

TL;DR: In this article, a generalized renewal process is used to derive an asymptotic approximation for the variance of the observed proportion of unsuccessful attempts on a trunk group during a given time-interval.
Abstract: The concept of a generalized renewal process is used to derive an asymptotic approximation for the variance of the observed proportion of unsuccessful attempts on a trunk group during a given time-interval. Calls are assumed to arrive according to a general renewal process, and those which are blocked leave the system and do not return (loss system). As an application of our result we examine the special case of an overflow input–an important example from telephone networks with alternate routing. Comparison of our results with values obtained from simulation indicates that the approximation is quite accurate for telephone traffic-engineering purposes.
