update.beta: Update beta vector

In aplantin/CSGL: Compositional Sparse Group Lasso

Description

This function uses the SGL package to minimize the augmented Lagrangian with respect to beta.

Usage

## S3 method for class 'beta'
update(y, Z, n, p, mu, alpha, xi, lambda, theta, groups)

Arguments

y	Outcome vector
Z	Matrix of log OTU proportions
n	Number of subjects (nrow(Z))
p	Number of OTUs (ncol(Z))
mu	Augmented Lagrangian parameter
alpha	p-vector of coefficients
xi	p-vector of Lagrange multipliers
lambda	Regularization parameter
theta	Defines convex combination between L1 and L2 penalties (theta = 1 is L1 only)
groups	Vector indicating group membership of each OTU

Value

Updated beta vector
