From: Optimal choice of word length when comparing two Markov sequences using a χ 2-statistic
The relationship between the word length k and the power of \(S_{k}^{R}\) based on NGS reads. The transition matrix of sequence A 1 is from Table 1 and the transition matrix of A 2 is from Table 2. The parameters of Table 2 are α 1=α 2=0.05,β 1=β 2=−0.05,γ 1=γ 2=0.03,δ 1=δ 2=−0.03. a homogeneous sampling without errors, b homogeneous sampling with errors, c heterogeneous sampling without errors, and d heterogeneous sampling with errors
