公司用EG,个人电脑装的PC版SAS 9.3。 出于数据保护的原因,我们的SAS运行都在公司的服务器上,EG是服务器上的操作界面。跟PC版的sas用起来相比,稍微有点不同。比如说,它有 run 和 run selection 两个选项,如果不点 run selection, 即时选中了想运行的程序对象,SAS运行的时候则默认是run整个程序。我刚用的时候,这里不知道,每次都纳闷为啥运行慢得很。再就是写函数/参数的时候,系统会根据字符的相似性给予提示。不过,也许跟我们公司的版本有关,proc iml并不识别。我只能在pc版9.3中run。
至于,各位提到的菜单等界面,我们其实从来不用。要快,要逻辑清楚,还是写code更有优势。
所以,我觉得不需要专门来学EG,举个不太严谨的例子,就好像用惯了windows xp,现在让你用windows7,只是有些地方需要适应而已。其它的并无。
(1) If you know how to use SAS eg, it would be very helpful for SAS developer because it could transfer very simple figure into SAS code.
(2) It is easy to do the code control because it can transfer your work into stored process.
(3) It has many advantage. Anyway, you need to understand Statistics first to use it.
From my own experience:
SAS EG is very useful for complicated and big-data style data analysis.
It is more efficient than SQL in terms of data processing speed.
