Statistical surveillance. Optimality and methods.
(University of Gothenburg, 2002-02-01)
Different criteria of optimality are used in different subcultures of statistical surveillance. One aim with this review is to bridge the gap between the different areas. The shortcomings of some criteria of optimality are ...
Statistical surveillance - Exponentially weighted moving average methods and public health monitoring
(University of Gothenburg, 2001-07-01)
The need for statistical surveillance has been noticed in many different areas and examples of applications include the detection of an increased incidence of a disease, the detection of an increased radiation level and ...
Characterization of methods for surveillance by optimality
(University of Gothenburg, 1999-12-02)
Different criteria of optimality are discussed. The shortcomings of some criteria of optimality are demonstrated by their implications. The correspondences between some criteria of optimality and some methods are examined. ...
Evaluation of multivariate surveillance
(2009-05-15)
Multivariate surveillance is of interest in many areas such as industrial production, bioterrorism detection, spatial surveillance, and financial transaction strategies. Some of the suggested approaches to multivariate ...
Evaluations of some exponentially weighted moving average methods
(University of Gothenburg, 2001-06-01)
Several versions of the EWMA (Exponentially Weighted Moving Average) method for monitoring a process with the aim of detecting a shift in the mean are studied both for the onesided and the two-sided case. The effects of ...
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 ...
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 ...
