Between and at transitions, benefits and premiums are paid, defining a payment process, and the technical reserve is defined as the present value of all future payments of the contract

A filtering method is proposed for extracting the underlying state given the time Markov chain, though a more useful equivalent deﬁnition in terms of transition rates will be given in Deﬁnition 6.1.3 below. Property (6.1) should be compared with the discrete time analog (3.3). As we did for the Poisson process, which we shall see is the simplest (and most important) continuous time Markov chain, we will attempt Basics of Markov Chains A random process is called a Markov Process if, conditional on the current state of the process, its future is independent of its past. If simply put , it is a mathematical model of a random phenomenon evolving with time in a way that the past affects the future only through the present.

### the Markov chain beginning with the intensity matrix and the Kolomogorov equations. Reuter and Lederman (1953) showed that for an intensity matrix with continuous elements q^j(t), i,j € S, which satisfy (3), solutions f^j(s,t), i,j € S, to (4) and (5) can be found such that for For a continuous-time homogeneous Markov process with transition intensity matrix Q, the probability of occupying state s at time u + t conditionally on occupying state r at time u is given by the (r,s) entry of the matrix P(t) = exp(tQ), where exp() is the matrix exponential. 3.2 Generator matrix type The typeargument speciﬁes the type of non-homogeneous model for the generator or intensity matrix of the Markov process. The possible values are 'gompertz', 'weibull', 'bspline'and 'bespoke'. Gompertz type A 'gompertz'type model leads to models where some or all of the intensities are of the form q rs(t;z) = exp( rs+ A multi--state life insurance model is naturally described in terms of the intensity matrix of an underlying (time--inhomogeneous) Markov process which describes the dynamics for the states of an insured person. Between and at transitions, benefits and premiums are paid, defining a payment process, and the technical reserve is defined as the present value of all future payments of the contract For a time homogeneous process, P(s, t) = P( t - s) and Q(t) = Q for all t 3 0. The long-run properties of continuous-time, homogeneous Markov chains are often studied in terms of their intensity matrices. We estimate a general mixture of Markov jump processes. The key novel feature of the proposed mixture is that the transition intensity matrices of the Markov processes comprising the mixture are entirely unconstrained.

### Matrix describing continuous-time Markov chains. In probability theory, a transition rate matrix (also known as an intensity matrix or infinitesimal generator matrix) is an array of numbers describing the instantaneous rate at which a continuous time Markov chain transitions between states. In a transition rate matrix Q (sometimes written A) element qij (for i ≠ j) denotes the rate departing from i and arriving in state j.

purpose, Markov chain Monte Carlo (MCMC) simulation algorithms for the  Matrix describing continuous-time Markov chains. In probability theory, a transition rate matrix (also known as an intensity matrix or infinitesimal generator matrix) is an array of numbers describing the instantaneous rate at which a continuous time Markov chain transitions between states.

### Intensity Matrix and Kolmogorov Diﬀerential Equations Stationary Distribution Time Reversibility Kolmogorov Diﬀerential Equations Let Λ be an intensity matrix on E, Λ i < ∞ and {X t,t ≥ 0} is the Markov jump process deﬁned on (Ω,F,P), then E ×E-matrices Pt satisfy the backward equation, i.e. (pt ij) ′ = X k∈E Λ ikp t kj = −Λ ip t ij + X k6= i Λ ikp t kj

For computing the result after 2 years, we just use the same matrix M, however we use b in place of x. Thus the distribution after 2 years is Mb = M2x. In fact, after n years, the distribution is given by Mnx. A process is Markov if the future state of the process depends only on its current state. i.e. P (X(t + s) = jjX(t) = i;X(u) = x(u);0 u
