     Hi
     
     maybe I found an error...:
     Please excuse errors in the labels, I am using a german version
     of SPSS and PSPP. I attached an image of what I mean and the .sav
     file.
     
     How to reproduce the "error":
     
        load mm.sav in spss (v21) and latest pspp
     
        choose cases -> by time / case
                choose case 1 to 100
     
        Analyse -> Descriptive Statistics -> Eplorative Data analysis
                Select "Nettomiete in EUR [nm]" as Dependent Variable
                From the "Statistics" Button chose "Descriptive" (with
     confidence of 95% in SPSS)
                (In SPSS I chose only in the OUTPUT area at the bottom
     "Statistics" -> no graphics)
     
        Please note in the output of both (see attached screenshot) that
     the trimmed mean is different!
     
     
     I do not understand why. Is this an error?
     
     
It certainly looks like something we need to investigate.  Thanks for 
pointing this out.
