From: Craig Johnson on
A lot of the data I work with is longitudinal data that is stacked. Before
analysis, I have to unstack it and re-label variables with a suffix to
indicate time of collection. I=92ve used proc transpose, data steps, and =
a
basic macro to unstack the data. I thought I=92d ask the experts what thei=
r
common methods of unstacking data was.



1) Code it using proc transpose

2) Data steps and merge all the sections together

3) Custom macro (automates proc transpose)

4) A method in PROC SQL I=92m not aware of?



Any advice to make the task easier would be appreciated!


Thanks!
