Optimal Surveillance Based on Exponentially Weighted Moving Averages [PDF]
Sequential Analysis, 2006 Abstract Statistical surveillance is used to detect an important change in a process as soon as possible after it has occurred. The exponentially weighted moving averages (EWMA) method is used in industry, economics, and medicine. Three optimality criteria of surveillance are studied.
