5 years ago Is Scan really a Markov State, or an event that happens during a cycle? Something like this:
Either way, you could have a variable pScan which varies the probability of scan by time by using:
- An if function, for example:
pScan = if(t==1 | t==5, 1, 0)This will return 1 in cycles 1 and 5 and 0 otherwise - A lookup table, for example:
pScan = tableScan[t,1]wheretableScanlooks like
| Index | Value |
|---|---|
| 0 | 0 |
| 1 | 1 |
| 2 | 0 |
| 3 | 0 |
| 4 | 0 |
| 5 | 1 |
| 6 | 0 |
and you would use the truncate option.
Would one of those approaches work?

How can I use tunnel states? For example, if a patient needs to have a scan at year 1 and 5, but not at years 2-4, how can I program it in Amua that when at year 1 and 5 the patient goes to 'Scan' in the Markov model, but at years 2-4 it goes to 'No Scan'. Thanks in advance!
