在SAS中创建新的总和和百分比列

Question

我有以下数据集：

con.setAutoCommit(false);

我想在SAS中为每个位置创建三个额外的列：雇员总数，警察百分比和消防员百分比。更新的数据集应如下所示：

Locations      Occupation
001            Teacher
001            Fireman
002            Teacher
002            Policeman
002            Fireman
003            Teacher
003            Teacher
003            Fireman
003            Policeman

谢谢！

Answer 1

只需使用sql即可获得摘要统计信息，然后与原始数据合并：

proc sql;
create table summary as 
select locations, count(*) as totalemployed, 
    sum(occupation='Policeman')/calculated totalemployed as percentpolice,
    sum(occupation='Fireman')/calculated totalemployed as percentfireman

from chk1
group by locations;
quit;

data final;
merge chk1 summary;
by locations;
run;
