SUM is one of the most frequently used SAS (R) functions for aggregating numeric variables. Althoughsummarizing data using the SUM function is a simple concept, it can become more complex when we deal with large data sets and many variables. This can sometimes lead to inaccurate results. ...
If that SUM function is then nested in a second SUM function, SAS produces a grand total of the calculated variable across all observations. In other words, the inner SUM function is performing the horizontal summation while the outer SUM function is performing the vertical summation. This ...

Explanation: when the SUM function is called with a single argument, it returns the value of that argument. In this case, it is called with a missing value, so it returns a missing value. Example 2ACredit = . ;BCredit = 1;TotalCredits = sum (ACredit, BCredit) + 2; What is the...
是一种在数据库中使用SUM函数进行求和计算,并结合条件进行筛选的操作。SUM函数用于计算指定列的总和,而条件则用于限定计算的范围。 在SQL中,可以使用WHERE子句来指定条件,以过滤需要计算的数据。下面是一个示例: 代码语言:txt 复制 SELECT SUM(column_name) FROM table_name WHERE condition; 其中,column_name是需要...

In SAS Viya, because you have a separate problem for each group, you could also use the BY statement in PROC OPTNETWORK (with MINCOSTFLOW) or the groupBy parameter in the runOptmodel action. in the dataset have, for each group, there is the distance between each subject and many a...
