Re: getting the confidence interval

[John Darrington]

The confidence interval is a concept associated with a hypothesis.
If it's the confidence interval on the test for a mean value, typically you 
would get that by using a T-Test.

     Folks,
     
     
     I would like to get a 95% confidence interval so that I could use it
     in AGGREGATE, e.g., 
     
       AGGREGATE OUTFILE * MODE ADDVARIABLES
         /BREAK=...
         /Mean = mean(V)
         /CI = ci(V, 0.95)
     
     What must I do to get the result of my hypothetical `ci' function?
     I'm a PSPP novice, so maybe there is a better solution than AGGREGATE
     ??? what I ultimately want is to emit the confidence interval of a
     variable to a CSV file using SAVE TRANSLATE.
