ludic

Overview

ludic is a package which implements Probabilistic Record Linkage methods that rely on the use of diagnosis codes only, in the absence of direct identifiers. On top of the CRAN help files and the function recordLink(), the following article explains what ludic is about:

ludic also implements an automated testing framework avoiding to select a given threshold for claiming a match in function atlas().
