Selecting Stopping Rules for Confidence Interval Procedures

Dashi I. Singham
2014 ACM Transactions on Modeling and Computer Simulation  
This article introduces methods for choosing and evaluating stopping rules for confidence interval procedures.  ...  Analysts often choose sequential stopping rules on an ad hoc basis to obtain confidence intervals with desired properties without requiring large sample sizes.  ...  Quality of the confidence interval is determined by its achieved confidence level and its precision (or half-width).  ...

2009 Proceedings of the 2009 Winter Simulation Conference (WSC)  
Sequential stopping rules applied to confidence interval procedures (CIPs) may lead to coverage that is less than nominal.  ...  Knowledge of coverage functions could help evaluate and compare confidence interval procedures while avoiding lengthy empirical testing.  ...  BACKGROUND We consider simulations that are used to estimate a confidence interval for some scalar mean level, µ, of system performance.  ...
