ranBin2 {binarySimCLF} | R Documentation |
Generates correlated binary vectors each of length 2. The routine is based on the pairwise odds ratio.
ranBin2(nRep, u, psi, seed)
nRep |
Number of replications. One can think of nRep as the number
of clusters with mean u and pairwise odds ratio psi . |
u |
Mean vector of length 2 |
psi |
Odds ratio. |
seed |
Sets the seed. |
Returns a response matrix of dimension nRep
by 2. Each row represents
an independent cluster.
# Examples u = c(0.25, 0.25); psi = 1.75; # Begin: checking whether the odds pairwise odds ratio is compatible with the # mean vector u. v = psi2var(psi,u); v cr = var2cor(v); cr cp = chkBinC(cr,u); cp$compat # End: checking compatibility. y = ranBin2(1000,u,psi) r = cor(y);r ybar = apply(y,2,mean);ybar psihat = cor2psi(r,ybar)$psi;psihat
