CheckStability {mlica}R Documentation

Tests stability of inferred ICA modes.

Description

Does a correlation test to see which of the inferred ICA modes are reproducible.

Usage

CheckStability(a.best.l, corr.th)

Arguments

a.best.l List of a.best objects from mlica runs.
corr.th Correlation threshold to use to decide whether a mode is reproducible.

Value

A list with the following components

stabM Vector of length ncp giving fraction of elements in a.best.l, for which correlation of the mode is larger than corr.th.
nI Number of elements in a.best.l.
