The meta4diag package provides tools to implement Bayesian bivariate meta-analyses of diagnostic test studies. meta4diag is a purpose-built front end of the R package INLA (Rue H., Martino S, and Chopin N. 2009). It allows the user a straightforward model specification and offers user-specific prior distributions. Further, the newly proposed penalized complexity prior framework (Simpson et al. 2014) is supported, which builds on prior intuitions about the behaviors of the variance and correlation parameters (Guo, J., Riebler, A. and Rue H. 2017). Accurate posterior marginal distributions for sensitivity and specificity as well as all hyperparameters, and covariates are directly obtained without Markov chain Monte Carlo sampling. Further, univariate estimates of interest, such as odds ratios, as well as the summary receiver operating characteristic (SROC) curve and other common graphics are directly available for interpretation. An interactive graphical user interface provides the user with the full functionality of the package without requiring any R programming.
