This is an example of an ADaM dataset designed to capture the reference data describing historical transitional probabilities.
In the example below, STRTM4 captures the combination of tobacco products of interest for this particular set of probabilities and STRTM5 captures the status of product(s) of interest at the time of first set of probabilities. STRTM6 captures the transition type of the combination of usage at the point of probability and STRTM7 captures the actual combination of usage at the point of probability
The rows 1-4 then follow the different probabilities of transitions following pathway "e" to "p" to "e" (NEVER/NEVER to CURRENT/CURRENT to FORMER/FORMER).
The rest of the rows show examples of various combinations and pathways of transitional probabilities that are captured in the historical data.
