A function for newton update of m This function calculate the first derivative of the elbo with respect to m for it's kth element.

Description

A function for newton update of m This function calculate the first derivative of the elbo with respect to m for it's kth element.

Usage

mk_fun(x, W_i, iSig, mu, vsquare, M, xi)

Arguments

x	kth element of m, variable of this function
W_i	ith observation.
iSig	inverse matrices of the variance parameter for the latent Gaussian variable.
mu	mean parameter for the latent Gaussian variable.
vsquare	diagonal elements of the variational parameter V.
M	sum of counts in K taxa for one observation.
xi	variational parameter xi, vector of n.

Examples

mk_fun()
