I have a simple program that extracts results from Paul Seed's 
-diagti- program and shoves them through -meta- or -metan- (as needed).  

The statistics meta-analyzed are:
  1) Likelihood of a Positive Test,
  2) Likelihood of a Negative Test,
  3) Sensitivity, and
  4) Specificity.

If this might be of interest to you, Jannik, I can send it your way.
