Description
This function performs a temporal ICA
Usage
ICAtemp(X,n.comp,alg.typ="parallel",centering=TRUE,hp.filter=TRUE)
Arguments
X
a matrix of size vm x tm which contains the functionnal images
n.comp
number of maximally independent components to extract
alg.typ
if 'alg.typ == "parallel"' the components are extracted
simultaneously (the default). if 'alg.typ == "deflation"' the
components are extracted one at a time.
centering
Logical. Should we center the data first. Centering
will be performed by firstly removing the column mean.
hp.filter
Logical. Should we perform high-pass filtering on the
data
Value
A list containing
time.seriesestimated source matrix of size n.comp x tm
spatial.componentsestimated mixing matrix of size vm x n.comp
