SAS：PROC TABULATE 重新排列 Header 个子组

Question

问题：如何控制PROC TABULATE输出中子组的顺序？

例如，假设我有这个输出，即 segment 内的 (A, B):

data example;
    input group $ segment $;
    datalines;
    1 A
    1 B
    2 A
    2 A
    3 B
    3 B
    ;
run;

proc tabulate data = example;
    class group segment;
    table group all, all = 'Total'*n segment*n;
run;

+-----------------------+------------+-------------------------+
+                       +            +         segment         +
+                       +            +------------+------------+
+                       +   Total    +     A      +     B      +
+                       +------------+------------+------------+
+                       +     N      +     N      +     N      +
+-----------------------+------------+------------+------------+
+    group              +            +            +            +
+-----------------------+            +            +            +
+    1                  +     2.00   +     1.00   +     1.00   +
+-----------------------+------------+------------+------------+
+    2                  +     2.00   +     2.00   +        .   +
+-----------------------+------------+------------+------------+
+    3                  +     2.00   +        .   +     2.00   +
+-----------------------+------------+------------+------------+
+    All                +     6.00   +     3.00   +     3.00   +
+-----------------------+------------+------------+------------+

我如何重新排列 segment 的子组以相反的顺序出现，(B, A)？

+-----------------------+------------+-------------------------+
+                       +            +         segment         +
+                       +            +------------+------------+
+                       +   Total    +     B      +     A      +
+                       +------------+------------+------------+
+                       +     N      +     N      +     N      +
+-----------------------+------------+------------+------------+
+    group              +            +            +            +
+-----------------------+            +            +            +
+    1                  +     2.00   +     1.00   +     1.00   +
+-----------------------+------------+------------+------------+
+    2                  +     2.00   +        .   +     2.00   +
+-----------------------+------------+------------+------------+
+    3                  +     2.00   +     2.00   +        .   +
+-----------------------+------------+------------+------------+
+    All                +     6.00   +     3.00   +     3.00   +
+-----------------------+------------+------------+------------+

似乎可以选择使用 DESC 或 DESCENDING= 对子组进行排序，但这些都不适合我。我的部分问题可能是我使用的术语。我不认为 "A" 和 "B" 在 SAS 词典中被称为子组。

Answer 1

如果您先对数据排序，然后对用户 order=data 进行排序，您应该能够得到您需要的内容：

proc sort data=example;
 by group descending segment;
run;

proc tabulate data = example order=data;
    class group segment;
    table group all, all = 'Total'*n segment*n;
run;
