Including a voxelwise covariate in 3dLME

There are a couple of issues with the model specification:

  1. The baseline variable is not included in the model formula using -model.

  2. It's unclear whether ambiguity, valence, and baseline vary within individuals. If they do, the model might not have been specified correctly. For more information and guidance on specifying individual-level random effects in hierarchical modeling, you may find this blog post helpful.

If you have any questions or need further clarification, feel free to reach out.
