8080 Formula for generating model expansions. By default, the
818132-parameter expansion will be generated. Note that any expressions
8282to be expanded *must* be in parentheses, even if they include only
83- a single variable (e.g., ``(x)^2``, not ``x^2``). Examples:
84-
85- * ``rps + wm + csf + gsr`` : 9-parameter model. ``rps`` denotes realignment
86- parameters, ``wm`` denotes mean white matter signal, ``csf`` denotes mean
87- cerebrospinal fluid signal, and ``gsr`` denotes mean global signal.
88- * ``(dd1(rps + wm + csf + gsr))^^2`` : 36-parameter expansion.
89- ``rps + wm + csf + gsr`` denotes that realignment parameters and mean
90- WM, CSF, and global signals should be included. ``dd1`` denotes that
91- these signals should be augmented with their first temporal
92- derivatives. ``^^2`` denotes that the original signals and temporal
93- derivatives should be augmented with quadratic expansions.
94- * ``(dd1(rps))^^2`` : 24-parameter expansion. ``rps`` denotes that
95- realignment parameters should be included. ``dd1`` and ``^^2`` denote
96- temporal derivative and quadratic expansions as above.
97- * ``(dd1(rps + wm + csf + gsr))^^2 + others`` : generate all expansion
98- terms necessary for a 36-parameter model as above, and
99- concatenate those expansion terms to all other regressor columns
