We pursue our series of blog articles illustrating rjags programs for diagnostic meta-analysis with an article describing how to carry out Bayesian inference for the Hierarchical Summary Receiver Operating Characteristic (HSROC) meta-analysis model (Rutter and Gatsonis(2001), Chu, Chen and Louis(2009)) when a perfect reference test is available. (For our previous article on the Bayesian bivariate model for diagnostic meta-analysis click here)
