Abstract:
|
Panel count studies are encountered in many fields such as business, in which the interest may be in monitoring insurance claims, in engineering, in monitoring lines of faulty code, and in medical research, in studying the occurrence of adenomas in the colon. Very few studies addressing design and sample size questions have been conducted. We build from an investigation of panel count studies versus continuous observation of individuals to provide guidance on design and sample size. We focus on rebalancing a study so that more individuals are recruited to both achieve the planned power and place followups at optimal times. Measures that will guide this rebalancing are discussed.
