robustWInit: Robust initialization of the W (affinity) matrix

In ACNE: Affymetrix SNP Probe-Summarization using Non-Negative Matrix Factorization

Robust initialization of the W (affinity) matrix

Description

Robust initialization of the W (affinity) matrix.

Usage

robustWInit(V, H, maxIter=50L, ...)

Arguments

V	An KxI matrix where I is the number of arrays and K is the number of probes where K should be even (K=2L).
H	A 2xI matrix of allele-specific copy-number estimates.
maxIter	The maximum number of iterations.
...	Not used.

Details

This function utilized a random number generator.

Value

Returns a Kx2 matrix of robustified probe-affinity estimates.
