Description This package implements a model for joint meta-analysis of sensitivity and specificity
of the diagnostic test under evaluation, while taking into account the possibly imperfect
sensitivity and specificity of the reference test. This hierarchical model accounts
for both within and between study variability. Estimation is carried out using
a Bayesian approach, implemented via a Gibbs sampler. The model can be applied in situations
where more than one reference test is used in the selected studies.
