Long-Term Frequency Interpretations 从频率学的角度来说,当试验次数 n 很大的时候,事件发生的频率同样可以表示事件发生的概率,那么 \pi_j=\lim_{n \rightarrow \infty}{\frac{v_{ij}(n)}{n}}, v_{ij}(n) 状态i 转移到到 j 的总次数。 记q_{kj}(n) 是状态 k\rightarrow j 的次数,那么有 ...
不过,对于 periodic Markov chain,其稳态分布不再表示 Markov chain 在无穷多步后处于状态 i 的极限概率,而只对应访问状态 i 的long-term frequency. 任意的 finite Markov chain 中都存在一个 recurrent 的 communicating class,其对应的 subchain 就会是 irreducible 并且 recurrent 的,如果其还是 aperiodic 的,...
Markov chainLong-term probabilityReservoirThe purpose of this article is to calculate the long-term or stable state of the Cerro Prieto dam volume through the use of first-order Markov Chains. A monthly analysis is realized to comply with the first order assumptions of the model. The behavior ...
As the time t increases, the probability of a pattern occurring might approach a steady-state distribution, which is the long-term probability of the system being in a particular state. The steady-state distribution is obtained by setting the probability of the state sequence at time t+1 equal...
A Markov chain exists when the probability of a future state depends on a previous state and when linked together forms a chain that reverts to a long-run steady-state level. This Markov approach is typically used to forecast the market share of two competitors. The required inputs are the...
≥ |λn|, hence λ2/λ1 is the dominant term. Random noise in the state distribution π can also speed up this convergence to the stationary distribution.[11] Reversible Markov chainA Markov chain is said to be reversible if there is a probability distribution over states, π, such that...

The aim of this paper is to analyze the prediction of infected people in long-term by analyzing the Covid-19 daily cases in an observation interval. By analyzing the daily cases of Covid-19 worldwide from December 31, 2019 until April 16, 2020, result shows that 61.43% of probability ...
Based on this interpretation, v_{ij}\left(n\right) is the long-term expected fraction of time that the state is equal to j . Expected Frequency of a Particular Transition(指定初始状态 j ,最终为特定状态 k 的稳态) Each time that state j is visited, there is probability \pi_{j}p_{...
Markov chain can be represented using a state diagram, where each node in the diagram represents a state and the edges between the nodes represent the transitions between the states. The probability of transitioning from one state to another is represented by the weight of the corresponding edge....
