# 6 Nov 2014 Intuitively, stationary means that the distribution of the chain at any step is the same. In other words, the chain is in equilibrium, there is no bias

A stationary distribution of a Markov chain is a probability distribution that remains unchanged in the Markov chain as time progresses. Typically, it is represented

2007-12-01 · The non-stationary Markov chain based on a parameterized joint density will be named P-NSFMC whereas the model based on a non-parameterized density is named NP-NSFMC. In this section we introduced a new fuzzy non-stationary Markov random chain model. We defined the associated prior joint density, initial and transition probabilities.

Non-stationary, four-state Markov chains were used to model the sunshine daily ratios at São Paulo, Brazil. Fourier series were used to account for the periodic seasonal variations in the transition probabilities. All the regressions and tests, based on Generalized Linear Models, were made through the software GLIM.

Hence, there is no stationary measure. More generally, if 0 … A non-stationary fuzzy Markov chain model is proposed in an unsupervised way, based on a recent Markov triplet approach. The method is compared with the stationary fuzzy Markovian chain model.

This Markov chain is stationary. However if we start with the initial distribution $P(X_0 =A)=1$.

### The 2-stringing of the resurrected Markov chain is used to supply stationary Markov representations of the killed and the absorbed Markov chains in an appropriate way, to compute their entropies and provide a clear interpretation. This is done in Sections 5.1 and 5.2 and in Propositions 3 and 4.

This paper is a continuation of investigations on the central limit theorem for nonstationary Markov chains, carried out by Markov (1910), Bernstein (1922–1936), Sapogov (1947–1949) and Linnik (1948–1949). Let $\Omega _i ,i = 1,2$, be sets of states of the chain, and $\mathfrak {A}_i$ be $\sigma $-algebras of measurable subsets of these sets. n is a Markov chain, with transition probabilities p i;i+1 =1 i m, p i;i 1 = i m. What is the stationary distribution of this chain?

### My current plan is to consider the outcomes as a Markov chain. If I assume that the data represents a stationary state, then it is easy to get the transition probabilities. The problem is, I don't believe that they are stationary: having "no answer" 20 times is a different situation to be in than having "no answer" once.

In addition to focusing on continuous-time, nonstationary Markov chains as models of individual choice behavior, a few words are in order about my emphasis on their estimation from panel For discrete-time Markov chains, two new normwise bounds are obtained. The first bound is rather easy to obtain since the needed condition, equivalent to uniform ergodicity, is imposed on the transition matrix directly. The second bound, which holds for a general (possibly periodic) Markov chain, involves finding a drift function. To obtain stable long run behavior in discrete time Markov chains, it is common to assume that the chain is aperiodic. This needs to be assumed on top of irreducibility if one wishes to rule out all dependence on initial conditions. Corollary 25 shows that periodicity is not a concern for irreducible continuous time Markov chains. Legrand D. F. Saint-Cyr & Laurent Piet, 2018.
