Hello, I am using 3dLME2 and it works great. It gives exactly the same results as when I extract a single voxel and analyze it with R. That is always reassuring.
I would like to also have the ICC and the Random Effect LRT results for every voxel. Is this possible? And if so, how can I calculate them?
Thank you for this info. I am sorry that did not find this on my own. I will read the associated paper also. When I do mixed models I report the LRT test results just to say that the use of the random effect was significant.

You raise an interesting question. Practically speaking, such information might be informative in one or a few brain regions, but it could become overwhelming or less meaningful when considered across the whole brain. More fundamentally, I believe that a statistical model should be constructed based on the hierarchical structure of the data, relevant theoretical constructs, and their underlying causal relationships. In particular, the inclusion of variation (e.g., random effects) should be guided by prior knowledge or shared understanding that such variation---like individual differences---is expected and meaningful.
