qpHist: Histograms of non-rejection rates

Description

Plots the distribution of non-rejection rates.

Usage

qpHist(nrrMatrix, A=NULL, titlehist = "all estimated\nnon-rejection rates", freq=TRUE)

Arguments

nrrMatrix

matrix of non-rejection rates.

A

adjacency matrix of an undirected graph whose present and missing edges will be employed to show separately the distribution of non-rejection rates.

titlehist

main title of the histogram(s).

freq

logical; if TRUE, the histograms show frequencies (counts) of occurrence of the different non-rejection rate values; if FALSE, then probability densities are plotted

Value

None

Details

This function plots histograms using the R-function hist and therefore the way they are displayed follows that of this R-function.

Sigma <- qpG2Sigma(A, rho=0.5)
X <- rmvnorm(nObs, sigma=as.matrix(Sigma))
