From: Craig Johnson on 25 Feb 2010 09:29 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!
