Description Usage Arguments Value Examples
An R wrapper for carrying out NSMMICA on nonparametric multivariate ICA mixture data.
1 2 3  EMFASTICAALG(DataMatrix, numCluster, h = 0, maxiter = 300,
icaiter = 150, tol = 1e06, verb = TRUE, combine = TRUE,
seednum = 82196, ...)

DataMatrix 
A matrix of which the rows are data entries. Its dimension is 
numCluster 
Predetermined number of mixing components 
h 
Bandwidth. If 
maxiter 
Maximum number of iterations. Default is 
icaiter 
Maximum number of ICA iterations in each step. Default is 
tol 
Threshold that defines convergence (of the outer loop). Default is 
verb 

combine 

seednum 
Seed number (default is 
... 
The returned value is an EMFASTICAALG
object which consists of a list of items:
$InputData 
A matrix of which the columns are data entries. Its dimension is 
$Lambdas 
A matrix where rows store estimated mixing weights from each iteration. 
$WMtrs 
List of 
$WUnmixZ 
List of unmixing matrices for whitened data for each of the m clusters. 
$OriginalSignals 
List of Recovered ICA components for each of the 
$ProductDensity 

$MembershipProbs 

$ObjValue 
Vector holding values of data loglikelihood. 
$ICABandWidth 
Matrix holding choices of bandwidth for original signals. 
$call 
The function call that results in the returned object. 
$time 
Computing time elapsed in second.
