Markov chain analysis ---------------------

^markov^ varname [ , ^f^name^(^string^)^ ^p^name^(^string^)^ tabchi_options ]

Description -----------

^markov^ examines varname, treated as a sequence or series, to produce basic summaries relevant to discrete-time, discrete-state Markov chains.

^markov^ tabulates one-step transition frequencies from one state to another, carries out a chi-square test for independence, and tabulates a transition probability matrix. The frequency matrix and the probability matrix are saved as F and P, or as whatever names are specified. Matrices with these names are overwritten.

It is the user's responsibility to ensure that data are in the appropriate sort order when ^markov^ is called.

^tabchi^ must be installed first.

Options -------

^fname(^string^)^ specifies a name for the frequency matrix (default F).

^pname(^string^)^ specifies a name for the probability matrix (default P).

tabchi_options are options allowed with ^tabchi^.

Example -------

. ^markov state^
