选择好key variable再进行compare是必要的,否则proc compare过程将只会进行没有任何主键的compare,极大的降低结果的可读性。其中,by语句会对每个by group进行分别的compare,一般不在我们的应用范围内。那么这时候,使用id语句就可以完成先匹配key variable再进行compare的过程。同样是以上数据集,加入USUBJID作为id变量的结...
These would be the variables sorted by. Did you try the OUTPERCENT or OUTDIF options? The data set will not look like your example. 0 Likes Reply alepage Barite | Level 11 Re: how to properly use proc compare Posted 08-20-2024 03:57 PM (610 views) | In reply to ballardw ...
2. Differences in variable count - missing variables. 3. Differences in data values - data values. For validation of any dataset, PROC COMPARE is your first choice. Not only are datasets compared but also listings and summary reports. For summary reports fromPROC REPORTfor example, plan to sa...
format. A programmer would like to create a new variable, ship_note, that shows a character value with the order_id,shipped date, and customer name. For example, given the first observation ship_note would have the value "Order 9341 shipped on 02FEB2009 to Josh Martin". Which of the ...

·FIRST.VARIABLE:同一个 BY 变量(组),若新的变量值第一次出现时,其 first.variable 值为 1。 ·LAST.VARIABLE:同一个 BY 变量(组),若新的变量值最后一次出现时,其 last.variable 值为 1。 另外,在 BY 变量右面有多个变量时,先按第一个变量排序,若第一个变量的观测存在重复时,才按第二个 变量排序。
系统宏变量回返回过程步的结果,有的时候非常有用。比如我们需要做一个宏工具,来扫描指定的两个逻辑库下,所有同名数据集是否相同。 这个时候我们需要程序自动读取过程步proc compare的信息。如果没有sysinfo,那么我们可能需要通过导出数据集,然后对比数据集得出结论。但是sysinfo这个宏变量可以让我们直接获取需要的信息。
Variable formats are handled by PROC COMPARE as it is used for comparing unformatted values. 22. What is the use of $BASE64X? By using $BASE64X encoding, the character data is converted into ASCII text. 23. What are the features of the SAS system?
