Monitoring Intervals between Rare Events: A Cumulative Score Procedure Compared with Rina Chen’s Sets Technique

Abstract

SummaryA cumulative score procedure (cuscore) is compared with Rina Chen’s sets technique. Cumulative score procedures make a faster detection of subtle epidemics of rare diseases possible. Besides, the implementation of this new sequential technique is very simple. Therefore, the use of the cuscore procedure instead of the sets technique is recommended.
