1995) can be summarized as follows.
consider a sequence X of length N. The maximum matching length L i is defined as: L i is the maximum common subsequence before and after i. IfL is the average length of L i , given bȳ then the method obtains the entropy rate h 1 as Given the true entropy rate h * , convergence has been mathematically proven for a stationary process, such that In this article, we consider this entropy rate h 1 as a constancy measure candidate.
