Longitudinal methods for analysis of the influence of breastfeeding on early child health in Pakistan
(University of Gothenburg, 1999-11-01)
Statistical methods for analysing aspects of early child health in Lahore, Pakistan are discussed. We construct generalised linear mixed models with a binomial response variable and both fixed and random explaining effects. ...
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. ...
Evaluations of likelihood ratio methods for surveillance. Differences and robustness.
(University of Gothenburg, 1998-02-01)
In many areas there is a need for continual observation of a time series, with the goal of detecting an important change in the underlying process as soon as possible after it has occurred. In recent years there have been ...
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 ...
Statistical surveillance of business cycles
(University of Gothenburg, 1994-01-01)
Methods for timely detection of turning-points in business cycles are discussed from a statistical point of view. The theory on optimal surveillance is used to characterize different approaches advocated in literature. ...
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 ...
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 ...
