Fig. 1From: Optimal choice of word length when comparing two Markov sequences using a χ 2-statisticRelationship between the word length k and the power. The transition matrix of sequence A 1 is from Table 1 and the transition matrix of sequence A 2 is from Table 2 with the parameters being (a) α i =β i =γ i =δ i =0.05, i=1,2 for the first order MC and (b) α 1=α 2=0.05, β 1=β 2=−0.05,γ 1=γ 2=0.03,δ 1=δ 2=−0.03 for the second order MCBack to article page
