Add information about the transition probabilities using the following table from the lecture notes:<br />

9. Start by clicking immediately underneath the”Active” terminal branch of the “Remission” branch of the<br />

<strong>Markov</strong> node, typing in “0.41,” and then “Enter.” Type in “0.00" for the transition probabilities for the<br />

terminal branches “Flare” and “Death.” Type in “#” for the transition probability for the terminal node<br />

“Remission.” The reason for this way of indicating probabilities will become obvious later in the exercise.<br />

Add the other transition probabilities to the other terminal nodes. Use the pound sign (#) for the transition<br />

probabilities for “Death” in the other terminal nodes.<br />

Add information about the initial distribution of patients<br />

The following table is from The lecture notes:<br />

10. To start, click underneath the “Remission” branch of the <strong>Markov</strong> node and type in “0.10.” Add<br />

numbers that correspond to the “Active” and “Flare”initial states, and use “#’ to indicate the value for<br />

“Dead.”<br />

Add values for the outcome variables<br />

11. In this example, we will use two outcome variables. The first outcome variable will be a cost variable.<br />

That variable is created using the probability of hospitalization, which is described in the following table<br />

from the lecture notes:<br />
