Statistical Inference
¡´ specific effects over the entire SPM
- How to interpret the SPM{t} in terms of p-values?
- Two types of the threshold:
(i) a critical height that the region has to reach.
(ii) a critical size that a region must exceed before it is considered significant.
- Gaussian random filed: SPM{t} ->SPM{Z}.
¡´ The p-value based on Z, the largest value in the region
- The threshold u can be chosen, and the optimum threshold should maximize sensitivity.
¡´ The p-value based on n, the size of the region
