37.4 Converting a Markov model to a State Transition Diagram

Since analyses are run on the Markov model in decision tree format, you might ask why you would want to convert a Markov model to a state transition diagram. Well, you might want a simpler representation of the Markov model for communication purposes. With a state transition diagram, it's easier to see the flow of patients among the health states.

To illustrate this process, you can open the Health Care tutorial example model Markov Cancer Decision.trex

To convert a Markov model to a state transition diagram:

• Select the Markov node in the decision tree, and then right click on the white space.

• Choose Convert to STD from the context menu.

The result is a new state transition diagram with all states and transition arcs. Note that there may be many paths from one state to another, but only one arc will be created.
