【SAS NOTE】OUTPUT

1 proc means data=mysas.ifthen11;
2     var year date gtone shen dong all;
3     output out=mysas.tryout max(gtone shen)=a b;
4     run;
5 proc print data=mysas.tryout;
6 run;

用output可以将means的结果另存到另一个数据集中。

1 proc means data=mysas.ifthen11;
2     var year date gtone shen dong all;
3     by year;
4     output out=mysas.tryout max(gtone shen)=a b;
5     run;

增加by 可以根据year进行分类统计。
