Hi,
I have a naïve question. When I use GLM for a single subject timeseries data, how the variance is evaluated to get the t value? I know the beta values and contrast matrix make the numerator for the t value. How is the denominator made? Is it through the fitting residual ie std(residual), or is it from session by session or run by run variance? Can I find the formula somewhere? I was not able to find the answer in tutorial or the existing mailing list. Thanks a lot!
Best,
Haoran
