PROC SQL 使用 ORDER BY 子句进行排序。PROC SQL 的排序非常灵活,支持根据单个变量或多个变量的组合进行排序,支持根据表达式的结果排序,甚至支持根据‘匿名变量’的结果进行排序。 例1: ↑向右滑动查看全部代码↑ 基于多变量的排序时,PROC SQL 根据排序变量出现的先后顺序,先排第一个变量,若某些观测的第一个变量的...
但现在我想知道 var c 的值在输出中看到的组合 (var a, var b) 旁边的前一组中代表什么。有办法找出来吗?我尝试按照 proc sort 进行排序,但我不知道它的工作方式是否与在 proc sql 中选择不同记录相同。proc sort data = work.dataset out = work.output2 NODUPKEY; by a b; run; Run...
什么是SAS中的PROC MIXED,你在项目中如何应用它? 如何在SAS中进行交叉验证(Cross-validation)? 你知道SAS中的PROC ARIMA吗?能够简要说明一下它的用途吗? 在SAS中,你如何执行数据集的排序(Sort)和索引(Index)操作? 你在实际项目中遇到过的最具挑战性的SAS编程问题是什么,你是如何解决的?
PROC SORT with NODUPKEY will always return the physical first record - ie, as you list the data, c=71 will be kept always. PROC SQL will not necessarily return any particular record; you could ask for min or max, but you could not guarantee the first record in sort order regardless ...
如果不知道观测值的总数,可以先用`proc sql`计算出总数,然后再执行打印过程。 2.使用WHERE选项:在`PROC PRINT`语句中使用`WHERE`选项来筛选出最后10个观测值。这需要先计算出数据集中观测值的总数,然后使用`WHERE`语句来筛选出最后10个观测值。 3.倒序排列:可以先将数据集倒序排列,然后使用`OBS=10`来打印前10...
proc sql; select compress(Name||"_Ref") into :name_list separated by ' ' from sashelp.vcolumn where libname = 'WORK' and memname = 'NAMES'; quit; This produces a space delimited macro vaiable with the desired names. Step 2 To build the empty data set then this code will work: ...
