Functions to fit a higher order Markov chain

Description

Given a sequence of states arising from a stationary state, it fits the underlying Markov chain distribution with higher order.

Usage

seq2freqProb(sequence)
seq2matHigh(sequence, order)

Arguments

sequence	A character list.
order	Markov chain order

Value

A list containing lambda, Q, and X.
