Howdy
How would I output the results from a proc means to a SAS data set? I know how to output out a mean of a collapsed variable but I also need to output out the standard deviation for each collapsed variable.
Here is what I can do:
proc means data=digit;
by x;
var y;
output out=means mean=ybar;
run;
Is there a statement I could use to create a std dev for y?
I appreciate any help someone could give me.
I'm not sure what you mean by collapsed variable but to add standard deviation to your output add
std= ystd after mean=ybar.
If you want to process more variables such as with :
var var1 var2 var3 ... ;
you could use
output out=<datasetname> mean= std= <other requested statistics> / autoname;
The autoname option will create variable names based on your variable name and the requested statistic so you don't have to.

thank ya.
by collapsed obs I was trying to say that the mean of y was generated by x over a basket of time points but did a poor job of communicating this
