Questions
1

Where can I find documentation about the methods used in the Classify command in Mathematica 10? Specifically, how does the method ‘Markov’ work?

Any pointers to the documentation for the methods available in Classify, or an explanation of how the method ‘Markov’ works, will be appreciated.

Got the answer, at least for the example given in the Documentation. I have posted the answer here on StackExchange Mathematica forum (I had asked the question there also):
