InferenceR: Postprocessing - Inference on the association matrix

In iBATCGH: Integrative Bayesian Analysis of Transcriptomic and CGH Data

Description

This function performs posterior inference on the association matrix, returning the matrix of posterior probabilities of inclusion for each association gene expression - CGH. It also returns the binary matrix of significant links that exceed a threshold given as argument.

Usage

InferenceR(listR, G, M, niter, burnin, threshold = 0.5)

Arguments

listR	First niter objects of the output of the main function
G	Number of gene expression probes
M	Number of aCGH probes
niter	Number of Monte Carlo Markov Chains iterations
burnin	Burn-in
threshold	Threshold on the posterior probability of inclusion

Value

A list made of the following items

FreqMat	Matrix of posterior probabilities of inclusion
final	Binary association matrix
