unique_paths function

Find all possible paths until absorption from a given starting state

unique_paths finds all possible sequences of states until absorption when the process has a tree-like structure.

unique_paths(from_state, tmat)

Arguments

• from_state: Initial state.

• tmat: A transition matrix describing the states and transitions in the multi-state model, as can be obtained by running transMat. See argument trans in msprep (mstate

  package) for more detailed information.

Returns

A matrix where each column is a sequence of states taken by the process until absorption. There are as many columns as the number of possible paths until absorption.
