x**g 发帖数: 807 | 1 Hi, I need some help here.
I used PROC SURVEYMEANS and I got the standard error of mean. How can I get
the standard deviation of mean?
Here is part of the output from PROC SURVEYMENAS.
Number of Clusters 91
Number of Observations 34572
Sum of Weights 34312.5015
The standard error of mean is 0.007918.
(BTW, the standard deviation from PROC MEANS is 0.725688)
Thanks a lot! |
