| Which is the optimisation method used in SPM?
Which bit of SPM? The parametric models used by the stats
are linear, so can be fitted by a single matrix inversion.
For the image registration parts, the fitting is done by
Gauss-Newton optimisation (with a few tweeks). Segmentation
uses an EM algorithm in the form of a mixture model cluster
analysis.
