Re: SPSS vs PSPP syntax

[Friedrich Beckmann]

Dear Douglas,

thanks for the reply and the new bug descriptions regarding t-test groups and the regression command. 

I opened a bug in the bug database regarding the regression syntax:

http://savannah.gnu.org/bugs/?45667

The spss v23 syntax description 

ftp://public.dhe.ibm.com/software/analytics/spss/documentation/statistics/23.0/en/client/Manuals/IBM_SPSS_Statistics_Command_Syntax_Reference.pdf

says that the groups command should separate the values with comma, but I guess you produced the syntax via the spss GUI, right? 

Regards

Friedrich

I am using version 22 of SPSS and it does not complain if I use CIN.   

I also noticed that SPSS V22 uses slightly different syntax for an independent samples t-test. SPSS produces:

T-TEST GROUPS=group(1 2)

  /MISSING=ANALYSIS

  /VARIABLES=score

  /CRITERIA=CI(.95).

which PSPP does not like.  PSPP wants group(1,2) but SPSS does not complain with group(1,2).

There seems to be more serious discrepancies between SPSS and PSPP syntax for linear regression. For a simple linear model SPSS produces

REGRESSION

  /MISSING LISTWISE

  /STATISTICS COEFF OUTS CI(95) R ANOVA

  /CRITERIA=PIN(.05) POUT(.10)

  /NOORIGIN

  /DEPENDENT y

  /METHOD=ENTER x.

while PSSS gives

REGRESSION
    /VARIABLES= x
    /DEPENDENT=     y
    /STATISTICS=COEFF CI R ANOVA.

SPSS V22 does not accept the PSPP regression syntax.

Dear Douglas,

thank you for the bug report. I filed a bug in the bug database of pspp:

As mentioned in the bug report the spss manual uses CIN in the examples. Does your spss version complain if you use CIN instead of CI?

 PSPP uses CIN(.95) rather than CI(.95).  I hope this is a bug and not intentional.
