【SAS NOTE】OUTPUT

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

用output可以将means的结果另存到另一个数据集中。

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

增加by 可以根据year进行分类统计。
