qpUnifRndAssociation: Uniformly random association values

In qpgraph: Estimation of genetic and molecular regulatory networks from high-throughput genomics data

Description

Builds a matrix of uniformly random association values between -1 and +1 for all pairs of variables that follow from the number of variables given as input argument.

Usage

qpUnifRndAssociation(n.var, var.names=as.character(1:n.var))

Arguments

n.var	number of variables.
var.names	names of the variables to use as row and column names in the resulting matrix.

Details

This function simply generates uniformly random association values with no independence pattern associated to them. For generating a random covariance matrix that reflects such a pattern use the function qpG2Sigma.

Value

A symmetric matrix of uniformly random association values between -1 and +1.
