ICAspat: ICAspat

Description

This function performs a spatial ICA

Usage

ICAspat(X,n.comp,alg.typ="parallel",centering=TRUE,hp.filter=TRUE)

Arguments

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 mixing matrix of size tm x n.comp
  • spatial.componentsestimated source matrix of size n.comp x vm
