Likelihood based methods for detection of turning points in business cycles - A comparative study
(University of Gothenburg, 2001-05-01)
Methods for on-line monitoring of business cycles are compared with respect to the ability of early prediction of the next tum by an alarm for a tum in a leading index. Three likelihood-based methods for turning point ...
Detection of turning points in business cycles
(University of Gothenburg, 2002-06-01)
Methods for on-line monitoring of business cycles are compared with respect to the ability of early prediction of the next turn by an alarm for a turn in a leading index. Three likelihood based methods for turning point ...
Statistiska varningssystem för hälsorisker
(2009-02-17)
Varningssystem behövs t.ex. vid intensivövervakning, smittskydd, miljörisker och kvalitetskontroll av vården.
Statistiska varningssystem signalerar när det skett en väsentlig ändring och man vet vilka egenskaper systemet ...
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 ...
Statistical Surveillance of Epidemics: Peak Detection of Influenza in Sweden
(2007-11-28)
A statistical surveillance system gives a signal as soon as data give enough evidence of an important event. We consider on-line surveillance systems for detecting changes in influenza incidence. One important feature of ...
Semiparametric surveillance of outbreaks
(2008-07-02)
The detection of a change from a constant level to a monotonically increasing (or decreasing) regression is of special interest for the detection of outbreaks of, for example, epidemics. A maximum likelihood ratio statistic ...
Semiparametric estimation of outbreak regression
(2008-07-02)
A regression may be constant for small values of the independent variable (for example time), but then a monotonic increase starts. Such an “outbreak” regression is of interest for example in the study of the outbreak of ...
Predictions by early indicators of the time and height of yearly influenza outbreaks in Sweden
(2007-12-13)
Aims: Methods for prediction of the peak of the influenza from early observations are
suggested. These predictions can be used for planning purposes. Methods: In this
study, new robust methods are described and applied ...
Some statistical aspects on methods for detection of turning points in business cycles
(University of Gothenburg, 2002-07-01)
Statistical and practical aspects on methods for on-line turning point detection in business cycles are discussed. When a method is used on a real data set, there are a number of special data problems to be considered. ...
Similarities and differences between statistical surveillance and certain decision rules in finance
(2007-12-13)
Financial trading rules have the aim of continuously evaluating available information in order to make timely decisions. This is also the aim of methods for statistical surveillance. Many results are available regarding ...
