我有一个数据集,它有两个变量,我试图从中创建新的组。第一个变量是" religiosity"第二个是" Av_Anti",两者都是数字变量。我试图创建组分为9组,低/中/高宗教信仰和低/中/高Av_Anti。
DATA LYING1;
SET LYING;
IF RELIGIOSITY = (1 OR 2) AND Av_anti <=3 THEN Rel_Anti = "LowR,LowA";
IF RELIGIOSITY = (1 OR 2) AND Av_anti (>3 AND <=7) THEN Rel_Anti = "LowR,MidA";
IF RELIGIOSITY = (1 OR 2) AND Av_anti >7 THEN Rel_Anti = "LowR,HighA";
IF RELIGIOSITY = (3 OR 4 OR 5) AND Av_anti <=3 THEN Rel_Anti = "MidR,LowA";
IF RELIGIOSITY = (3 OR 4 OR 5) AND Av_anti (>3 AND <=7) THEN Rel_Anti = "MidR,MidA";
IF RELIGIOSITY = (3 OR 4 OR 5) AND Av_anti >7 THEN Rel_Anti = "MidR,HighA";
IF RELIGIOSITY = (6 OR 7) AND Av_anti <=3 THEN Rel_Anti = "HighR,LowA";
IF RELIGIOSITY = (6 OR 7) AND Av_anti (>3 AND <=7) THEN Rel_Anti = "HighR,MidA";
IF RELIGIOSITY = (6 OR 7) AND Av_anti >7 THEN Rel_Anti = "HighR,HighA";
ELSE Rel_Anti = "Error";
RUN;
我一直收到消息
"The function AV_ANTI is unknown, or cannot be accessed."
问题是,我已检查过该变量,其拼写正确且在被调用的数据集中列出。我不知道为什么SAS不会将其识别为变量?我似乎也遇到了逻辑运算符的一些问题(&gt;,&lt; =)。我错过了什么吗?
答案 0 :(得分:7)
您的比较/范围中包含无效的SAS语法。 您应该使用IN运算符检查是否包含在值列表中,然后将每个变量与每个比较的边界进行比较。 (即不是 不是:
Av_anti (>3 AND <=7)
但是:
Av_anti>3 and Av_anti<=7
或:
3<AV_atni<=7
以下内容应该有效。我也认为如果不是全部,那么你打算拥有其他的,否则你的最后一个条件将全部设置为Error或LowR / MidA。
DATA LYING1;
SET LYING;
IF RELIGIOSITY in (1, 2) AND Av_anti <=3 THEN Rel_Anti = "LowR,LowA";
ELSE IF RELIGIOSITY in (1, 2) AND (Av_anti >3 AND AV_anti<=7) THEN Rel_Anti = "LowR,MidA";
...
ELSE Rel_Anti = "Error";
RUN;
更好的解决方案可能是:
Data lying1;
set lying;
IF RELIGIOSITY in (1, 2) then P1='LowR';
else IF RELIGIOSITY in (3, 4, 5) then P1='MidR';
else IF RELIGIOSITY in (6,7) then P1='HighR';
else P1='Error';
if av_anti<=3 then P2='LowA';
else if 3<av_anti<=7 then P2='MidA';
else if AV_Anti>7 then 'HighA';
else P2='Error';
Rel_Anti=catx(",", P1, P2);
run;
