Empirical Bayes Estimation in Nonstationary Markov chains
Estimation procedures for nonstationary Markov chains appear to be relatively sparse. This work introduces empirical Bayes estimators for the transition probability matrix of a finite nonstationary Markov chain. The data are assumed to be of a panel study type in which each data set consists of a sequence of observations on N>=2 independent and identically dis...
متن کاملGusztáv MORVAI and Benjamin WEISS: Order Estimation of Markov Chains
We describe estimators χ n (X 0 , X 1 ,. .. , X n), which when applied to an unknown stationary process taking values from a countable alphabet X , converge almost surely to k in case the process is a k-th order Markov chain and to infinity otherwise.
متن کاملNote: Maximum Likelihood Estimation for Markov Chains
1 Derivation of the MLE for Markov chains To recap, the basic case we’re considering is that of a Markov chain X∞ 1 with m states. The transition matrix, p, is unknown, and we impose no restrictions on it, but rather want to estimate it from data. The parameters we wish to infer are thus them matrix entries pij , which are defined as pij = Pr (Xt+1 = j|Xt = i) (1) What we observe is a sample fr...
