Editing Examples of Markov chains (section)

=== A model of language ===
This example came from Markov himself.<ref>Markov, A. A. "An example of statistical analysis of the text of eugene onegin illustrating the association of trials into a Chain." ''Bulletin de lAcadamie Imperiale des Sciences de St. Petersburg, ser'' 6 (1913): 153162.</ref> Markov chose 20,000 letters from Pushkin’s ''[[Eugene Onegin]]'', classified them into vowels and consonants, and counted the transition probabilities.<math display="block">\begin{array}{lll}
 & \text{vowel} & \text{consonant} \\
\text{vowel} & .128 & .872 \\
\text{consonant} & .663 & .337
\end{array}</math>The stationary distribution is 43.2 percent vowels and 56.8 percent consonants, which is close to the actual count in the book.<ref>''[https://math.dartmouth.edu/~prob/prob/prob.pdf Grinstead and Snell’s Introduction to Probability]'', page 465</ref>
