Dear SPM'ers,
We have a PET study with 8 subjects and two scans per subject, with 7
degrees of freedom in the analysis. How do the low degrees of freedom
affect the statistics of this design using SPM? Is SnPM particularly
suitable analysis framework in this case, or do the low degrees of freedom
hamper it as well? Is SnPM equally appropriate for a split-plot design (2
groups with 8 subjects each; two scans per subject)?
Thanks,
Esa Wallius
