I am attempting to run a model with clustered data (children within a family) using the cluster option and type = complex. When I run the model with the cluster option and the type=complex I get an error saying I have zero observations. When I remove the cluster option and type=complex then it works just fine.
What am I doing wrong?
Here is the error: *** ERROR The number of observations is 0. Check your data and format statement. Data file: R:\AlexJensenresearch\catsemstack.dat *** ERROR Invalid symbol in data file: "" at record #: 1, field #: 1
