Thanks, Jason.
Using the syntax below, I do, indeed, obtain the desired statistics and
the variables PRED and RESID are created. Now, how do I get the
scatterplot using PRED and RES without leaving PSPP?
Thanks again,
David

With the REGRESSION procedure, the syntax would be something
like this:
REGRESSION
/VARIABLES= educ
/DEPENDENT= happy
/STATISTICS=COEFF R ANOVA
/SAVE= PRED RESID.
You can then make scatterplots using residuals and predicted values.

Hello,
I'm the guy trying to fit a line to a scatterplot in PSPP.
John Darrington suggested it might be done using the REGRESSION
procedure with "...a bit more manual work".
What would that work be? What steps should I follow?
I understand that the syntax in SPSS would be something like:
* Curve Estimation.
TSET NEWVAR=NONE .
PREDICT THRU END.
CURVEFIT /VARIABLES=happy WITH educ
/CONSTANT
/MODEL=LINEAR
/PLOT FIT.
but, of course, that doesn't work in the version of PSPPIRE 0.7.2 that I
have been using
At the moment I must move the data to Open Office Calc, do the
regression using that program and then insert a line. I would rather
just stay in PSPPIRE 0.7.2 if possible.
Thanks for your help and for all the good work you have been doing

Hello,
A Windows user is asking me if there is some way to fit a curve to a
scatterplot on PSPP. I don't think it is possible
so far, but I don't know for sure.
Is there some way to do this?
Not exactly. The procedure would be CURVEFIT, which we don't currently
implement.
But the job could be done with the REGRESSION procedure - the user just
has to do a bit more manual work.
