varpar_fun: A function to update the variational parameters.

In yuanfang90/LNMVGA: Cluster microbiome / compositional data using a mixture of logistic-normal multinomial models

A function to update the variational parameters.

Description

This function use the newton update realted function and perform update on the variational parameters in one iteration.

Usage

varpar_fun(W, m, V, mu, iSig, K, z)

Arguments

W	observation data: the count data, n*(K+1) matrix where K is the number of taxa.
m	variational parameter m from last iteration.
V	variational parameter Vfrom last iteration.
mu	mean parameter for the latent Gaussian variable, list of g vectors of (K+1).
iSig	(generalized) inverse variance parameter for the latent Gaussian variable, list of g (K+1)*(K+1) matrices.
K	number of taxa.
z	class membership matrix at the current iteration.

Examples
