In BayesMultMeta: Bayesian Multivariate Meta-Analysis

Computes the split-\hat{R} estimate based on the rank normalization

Description

The function computes the split-\hat{R} estimate based on the rank normalization.

Usage

split_rank_hatR(MC)

Arguments

MC	An N \times M matrix with N draws in each of M constructed Markov chains.

Value

a value with the the split-\hat{R} estimate based on the rank normalization

Examples

dataREM<-mvmeta::hyp
# Observation matrix X
X<-t(cbind(dataREM$sbp,dataREM$dbp))
p<-nrow(X) # model dimension
n<-ncol(X) # sample size
# Matrix U
U<-matrix(0,n*p,n*p)
for (i_n in 1:n) {
  Use<-diag(c(dataREM$sbp_se[i_n],dataREM$dbp_se[i_n]))
  Corr_mat<-matrix(c(1,dataREM$rho[i_n],dataREM$rho[i_n],1),p,p)
  U[(p*(i_n-1)+1):(p*i_n),(p*(i_n-1)+1):(p*i_n)]<- Use%*%Corr_mat%*%Use
}
# Generating M Markov chains for mu_1
