When looking at the resulting bucket dataset, I find that the coefficients for the SA regressor (stim_label 1) are very different from GLT 4, which includes only the SA regressor. Why are they different? What is the GLT test doing in this case? I included it because the results of my other GLTs look really good, as expected, but the results for the SA regressor look weak and confusing - not what I expected - and I was confused, and testing things out to see what would happen.
