In VBmix: Variational Bayesian Mixture Models

Description

Usage

getQforComp(loadings, tau = 1, verbose = FALSE, quick = FALSE)

Arguments

loadings	aligned factor matrix.
tau	diagonal noise used for KL computations.
verbose	if TRUE maximal info is displayed.
quick	if TRUE, column norm values are used instead of KL computations (less accurate but faster).

Value

rank associated with loadings.
