Summary This paper proposes an alternative statistical method to capture-recapture in order to estimate under-ascertainment in the collection of ALS data for a disease registry in Ohio. The study utilized three statistical methods (z-score, straight section in a series, and Jenk’s natural breaks) to identify reference counties in Ohio with normal case-population relationships to build a model to estimate case counts in target counties with unrecruited cases. The researchers believe that this method has advantages over capture-recapture that allow it to be used to identify disease hotspots and associations between ALS and environment.
