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 . |
