getting the confidence interval

2018-10-12 Thread Werner LEMBERG
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
