MCmat: MCmat

In bryandmartin/MicrobiomePack: Tools for Microbiome data analysis

Description

This function simulates MC step for an entire matrix. Should not need to be used by user directly. NOTE: currently written in parallel

Usage

MCmat(Y, W, eY, N, Q, base, sigma, MCiter, stepsize = 1, poorman = FALSE)

Arguments

Y	logratio matrix
W	corresponding count matrix
eY	current expected value of logratio matrix
N	number of samples, or nrow of Y
Q	number of OTUs minus the base, or ncol of Y
base	OTU index used for base
sigma	current estimate of sigma
MCiter	number of MC samples to generate
stepsize	variance used for MH samples, defaults to 1. Tweak to adjust acceptance ratio
poorman	boolean of whether to just use simple diagonal inverse to calculate sigma inverse. Defaults to FALSE
