However, I would like to summarize the data per quarter in SAS. The problem I am having is that if for a country the same quantity is given twice (within the quarter) then PROC MEANS only take one of the two quantities. So I am missing data. Is there a way to fix this pr...
将生成所需的输出。如果能有更多的示例数据就好了。
The effects of the treatments (1 means effective; 0 means not effective) and the cost for each visit are recorded. Other than the two simulated datasets, two datasets shipped with SAS, SASHELP.CLASS and SASHELP.CARS, are also used in the paper. ***(0.2) Simulate a dataset for hospital...

While many SAS programmers may be accustomed to accomplishing these aggregation tasks with PROC SUMMARY (or equivalently, PROC MEANS), PROC SQL can also do a bang-up job of aggregation – often with less code and fewer steps. This step-by-step paper explains how to use PROC SQL for a ...
