Re: Cronbach's alpha and sample size

Dear Gregor, thank you very much for your comments. Due to possibly existing general interest I post this message also in sci.stat.edu. "Gregor Socan" [EMAIL PROTECTED] wrote You obviously should not use coefficient alpha. First, if an exclusion of some people causes such a change, then

FYI: data sets to check accuracy of stat packages

This may have already been discussed but there is web site from the National Institute of Standards that gives datasets for comparing the accuracy of statistics packages. In some cases even SAS did not do well. The URL is www.nist.gov/itl/div898/strd/ Mark Eakin Associate Professor

Distribution transformation - log odds

I am trying to determine the transform from log odds to the original scale. Assuming that I have x such that lo(x) is ~N(m,s^2) where lo(x) = ln[x/(1-x)], is there a closed form to calculate the moments on x given m and s? George Scott
