residuals in the regression command

[roxana dragan]

Hello,

I want to use the residuals in a regression. The residuals for me is the
difference between the dependent variable and the predicted variable. I
have found three types of residuals and I do not know which one is the one
I need.

1. standardized residuals (*zresid)- probably the residuals one get when
you get the standardized coefficients - I do not think I want that.

2. deleted residuals (*dresid) - I do not know what these can be.

3. studentized residuals (*sresid).

4. studentized deleted residuals (*sdresid).

Maybe somebody can direct me to a good web source that explains the spss
commands, I do not have access to the SPSS guide?

Thank you,
roxana

Hi Roxana,

It is the fifth of the three, Unstandardized.

The syntax to save them is like

REGRESSION /DEPENDENT y /METHOD=ENTER x1 x2 x3
  /SAVE RESID .

Regards

Jan

Roxana,

If you have access to SPSS, which you obviously do, you can get a lot of
information from the HELP menu.  Click on HELP, and search the index for
residuals.  In the regression documentation, the various residuals are
defined.
