Abstract

An overview of surveillance/monitoring in different areas will be given. Even though methods have been developed under different scientific cultures, the statistical concepts can be the same. The aim in all areas might be detection of an important change in an underlying process as soon as possible after the change has occurred. When the statistical problems are the same, progress in one area can be used also for other areas. Applications often contain complexities such as e.g. gradual changes or multivariate settings. Approaches to handling some complexities will be discussed. The correspondence between the evaluation measures and the aims of the application is important. Thus, the choice of evaluation measure deserves concern. The commonly used ARL criterion should be used with care. Strictly used, it can lead to methods, which are useless in practice.
