GLMM Logit link - error message

[Made]

Hello

I am working on a research with logistic regression, but when I enter some extra variables to a model which ran just fine, I receive the following message:
glmm: There are no valid records for the LOGIT link function. No output will be displayed. Execution of this command stops.

I am working with SPSS 23. It is a rather small database I am working with, but I would be surprised if that was the cause of all trouble. The Syntax I am using is the following:


DATASET ACTIVATE DataSet1.
*Generalized Linear Mixed Models.
GENLINMIXED
  /DATA_STRUCTURE SUBJECTS=mergeid REPEATED_MEASURES=DummyVignetteAdemhaling*

Is there anybody familiar with this error and, more important, has a solution? Thanks in advance.

Just out of curiosity, do I read your repeated measures subcommand as analyzing a 5 way interaction with 8 independent variables? I haven't analyzed a dataset with repeated measures of a dichotomous variable (or variables) so maybe I'm misunderstanding the syntax construction. If it is really a 5 way interaction and if each variable is dichotomous, then isn't that 32 cells (2**5). What is your dataset size?

Seems like your data are too sparse for the model you parameterized.

Without knowing anything about your study, I can say that:

"REPEATED_MEASURES=DummyVignetteAdemhaling*DummyVignetteConcentratie*DummyVignHoofdpijn*DummyVignetteSlaap*DummyVignetteStappen
  COVARIANCE_TYPE=DIAGONAL"

...is very likely an incorrect residual variance covariance structure specification.

Remove that piece of the code, try to fit the model again, and report back if you are still receiving an error message.
