Help functions for transition matrix
Help functions to get insight into the structure of a transition matrix.
trans |
Transition matrix, for instance produced by |
Function to.trans2 simply lists the transitions in trans in a
data frame; function trans2Q converts trans to a Q
matrix, the (j,k)th element of which contains the (shortest) number of
transitions needed to travel from the jth to the kth state; function
absorbing returns a vector (named if trans contains row or
columnc names) with the state numbers that are absorbing; function
is.circular returns (a Boolean) whether the transition matrix
specified in trans is circular or not.
