SAS技术

1. 用tabulate制作数据透视表

/*百分比输出格式*/
proc format;
    picture pctfmt low-high="009.9%";
run;

proc tabulate data=sashelp.cars;
    class type;
    var invoice horsepower enginesize;
    table type all, 
        (invoice horsepower enginesize)*(mean min max) n pctn*f=pctfmt.;
run;

2. 用sql制作报表

proc sql;
    select 
        sex,
        sum(case when weight>85 then 1 else 0 end) as weight85_cnt label="cnt weight>85",
        sum(case when weight>85 then 1 else 0 end)/count(1) as ratio label="weight>85 percent" format=percent8.2,
        sum(case when weight>95 then 1 else 0 end) as weight85_cnt label="cnt weight>95",
        sum(case when weight>95 then 1 else 0 end)/count(1) as ratio label="weight>95 percent" format=percent8.2
        
    from sashelp.class
    group by sex
    ;
quit;
