RRate: Estimating Replication Rate in GenomeWide Association Studies
About RRate 
Replication is a common validation method in GWAS. We regard an association as true finding when it shows significance in both the primary and replication studies. A worth pondering question is: what is the probability of a primary association (i.e. statistically significant association in the primary study) being validated in the replication study? We propose a Bayesian probabilistic measure named Replication Rate (RR) to answer this question.
