Level 2 residuals SPSS Mixed

[Tino Nsenene]

Hello,

I am estimating a twolevel regression model in SPSS using the mixed procedure
and would like to plot the level-2 residuals; however, I only get residuals
for the observations at level-1.
Can anyone help me how to obtain level-2 residuals in SPSS mixed?

Many thanks,
tino

Tino,

Add the following sub-command to your MIXED syntax: 

/SAVE FIXPRED 

Then use COMPUTE:

COMPUTE residual_level_2 = <insert dependent variable here> - FIXPRED_1.

EXECUTE.

Residuals = data – estimated mean

Calculate and then plot.

Tino,

Actually, the name produced for the predicted fixed values is FXPRED_1, not FIXPRED_1. With that in mind, assuming your dependent variable name is y, then:

COMPUTE residual_level_2 = y - FXPRED_1.

EXECUTE.

Want more details about the two types of predicted values to which you are indirectly referring? See a message I posted a while back here:

HTH.
