Directly known subclasses:
NmfSnpPlm

public abstract static class NmfPlm
extends ProbeLevelModel

This class represents the NMF model of [REF].

Usage

NmfPlm(..., maxIter=10L, maxIterRlm=20L, refs=NULL, flavor=c("v4", "v3", "v2", "v1"))

Arguments

...	Arguments passed to ProbeLevelModel.
maxIter	The maximum number of iteration in the NMF step.
maxIterRlm	A positive integer specifying the maximum number of iterations used in rlm.
refs	An index vector (integer or logical) specifying the reference samples. If NULL, all samples are used as a reference.
flavor	(Internal/developmental only) A character string specifying which algorithm to use.
