Graphical evaluation of statistical surveillance
(2003-10-01)
A computer program which simultaneously gives graphical information on important characteristics of statistical surveillance methods is presented. Surveillance, that is continual observation of a time series with the goal ...
COMPARISON BETWEEN TWO METHODS OF SURVEILLANCE: EXPONENTIALLY WEIGHTED MOVING AVERAGE VS CUSUM
(University of Gothenburg, 1993-01-01)
When control charts are used in practice it is necessary to know the characteristics of the charts in order to know which action is appropriate at an alarm. The probability of a false alarm, the probability of successful ...
CHARACTERIZATION OF METHODS FOR SURVEILLANCE BY OPTIMALITY
(University of Gothenburg, 1994-02-01)
Different criteria of optimality are discussed. The shortcomings of some earlier criteria of optimality are demonstrated by their implications. The correspondences between some criteria of optimality and some methods are ...
Evaluations of likelihood ratio methods for surveillance
(University of Gothenburg, 1996-03-01)
Methods based on likelihood ratios are known to have several optimality properties. When control charts are used in practice, knowledge about several characteristics of the method is important for the judgement of which ...
ON PERFORMANCE OF METHODS FOR STATISTICAL SURVEILLANCE
(University of Gothenburg, 1994-07-01)
Statistical surveillance is used to detect a change in a process. It might for example be a change of the level of a characteristic of an economic time series or a change of heart rate in intensive care. An alarm is triggered ...
VISUAL EVALUATIONS OF STATISTICAL SURVEILLANCE
(University of Gothenburg, 1994-03-01)
A computer program which simultaneously gives visual information on important characteristics is presented. Surveillance, that is continual observation of a time series with the goal of timely detection of possible important ...
Evaluation of univariate surveillance procedures for some multivariate problems
(University of Gothenburg, 1996-04-01)
The continual surveillance to detect changes has so far received large attention in the area of industrial quality control, where the monitoring of manufacturing processes to detect decreases in quality play an important ...
