SAS-压缩多行，保持最高价值

Question

我正在努力完成以下任务。我尝试过使用数组和排序，但似乎没有任何帮助 work.Any 将不胜感激。

Acct     Score1   Score2
9999       45       78
9999       58       65
8888       43       80
8888       43       90
8888       31       70

This is what I would like to end up with
Acct     Score1     Score2
9999       58         78
8888       43         90

所以基本上，保持每个帐户的最高分。

Answer 1

只需使用PROC MEANS。

proc means data=have nway ;
  class acct ;
  var score1 score2 ;
  output out=want max= ;
run;

Answer 2

我会推荐 PROC SQL:

PROC SQL;
    CREATE TABLE want AS 
        SELECT Acct, 
            MAX(Score1) AS Score1, 
            MAX(Score2) AS Score2
        FROM have
            GROUP BY Acct;
QUIT;
