- Hi!
-
- The dataset is structured like this:
-
- OBS Date x1 x2 ... xn N_12Mo
- 1 04/12/82 1 0 1
- 2 04/21/82 1 1 0
- 3 04/28/82 0 0 1
- .
- .
- .
- K
-
-
-
- Variable N_12Mo should indicate the number of observations that are
- less than a year old. In other words, how many lines above observation K
- are less than a year old. We used the LOOKUP procedure in Microsoft Excel.
- How could it be done in SAS?
-
- Thanks,
-
- Stephane
