John, Sorry for the delay.
Attached is the SPSS output. I also ran PSPP and I notice that PSPP calculates negative SS for this analysis, which produces negative MS, Negative F's, etc. If I add "select if( not sysmis(agree_score))." before GLM, I reproduce the SPSS output. Seems like not treating missing values is part (or the entirety?) of the problem? I wondered if perhaps SPSS 24 might mark missing values in a new way that is confusing to PSPP? But that's pure hypothesizing... -Alan On 5/28/2016 3:43 AM, John Darrington wrote: > On Fri, May 27, 2016 at 12:11:20PM -0500, Alan Mead wrote: > > > From the output, it's possible this is all (or much) of the issue is due > to the df being calculated wrong.
