Hello Fellow SAS users:
The survival node allows us to specify data in: Standard, Change-Time and Fully Expanded format respectively.
I am looking for examples (data step preferably or macro ) on how to create a "Fully Expanded" data set using _T_, ID, TIME-ID variables etc...
An example of such data set is the churn_fullyexpanded_monthly (below) in the SAMPSIO sample library.
If you have a piece of code you can share, I would truly appreciate it. I thank you in advance.
