Partial correlation: How to write the corrected values?

Dear SPSS experts

I had computed a partial correlation between 2 variables while controlling
for a third variable. Now I would like to get the corrected values in order
to do a scatterplot. I could not find the option "save". Under the
regression button, I could not find a partial regression model.

Which is the easiest way to do this in SPSS?

Thanks in advance
Best regards
Juergen

Dear Juergen,

In the REGRESSION window (which is for both simple and multiple
regression) you could click 'Plots' and 'Produce all partial plots'.
One of the two scatter plots you get by this is the one you ask for.
You can test this by dobbelt clicking the plot and click on 'Elements'
and 'Fit line at total' (and squaring the R2 displayed for this model).
And if you will have the new variables calculated you can regress Y on
Z and X on Z while saving the residuals from these analyses.

Best,
Henrik

In reply to this post by Juergen Haenggi

Dear all,

I answered this e-mail yesterday, but discovered a silly fault. Below,
I have corrected this and, besides, made an addition.

In the REGRESSION window (which is for both simple and multiple
regression) you could click 'Plots' and 'Produce all partial plots'.
One of the two scatter plots you get by this is the one you ask for.
You can test this by dobbelt clicking the plot and click on 'Elements'
and 'Fit line at total' (and taking the square root of the R2 displayed
for this model). And if you will have the new variables calculated you
can regress Y on Z and X on Z while saving the residuals from these
analyses. You can also, in the REGRESSION procedure under 'Statistics'
ask for 'Part and partial correlations' (which gives you the zero order
correlation too).

Best,
Henrik
