cluster_pep: Get the Clusterwise Posterior Exchangeability Matrix
In basket: Basket Trial Analysis

MEM analyses include the posterior exchangeability probability (PEP) of clusters of arms giving the probability that any two arms are exchangeable. This function returns the matrix of those probabilities.
