SEQUENTIAL ANALYSIS OF SIMPLE HYPOTHESES WHEN USING PLAY-THE-WINNER ALLOCATION
(University of Gothenburg, 1996-01-01)Play-the-winner allocations aim to place more subjects on the better treatment. The subjects enter the study sequentially. In this paper, a method for analyzing a dichotomous response, when using the randomized play-the-winner ... -
Some principles for surveillance adopted for multivariate processes with a common change point
(University of Gothenburg, 1996-02-01)The surveillance of multivariate processes has received growing attention during the last decade. Several generalizations of well-known methods such as Shew hart , CUSUM and EWMA charts have been proposed. Many of these ... -
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 ... -
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 ... -
Outlying observations and their influence on maximum pseudo-likelihood estimates of Gibbs point processes
(University of Gothenburg, 1996-05-01)Maximum pseudo-likelihood estimation method is an attractive method to estimate interaction parameters of Gibbs point processes. A drawback of the method is that it tends to overestimate interaction if there is strong ... -
Sequential probability ratio tests when using randomized play-the-winner allocation
(University of Gothenburg, 1997-01-01)In many clinical experiments there is a conflict between ethical demands to provide the best possible medical care for the patients and the statisticians desire to obtain an efficient experiment. Play-the-winner allocations ... -
Monitoring a Freshwater Fishpopulation: Statistical Surveillance of Biodiversity
(University of Gothenburg, 1997-02-01)Statistical surveillance are methods for repeated analysis of stochastic processes, aiming to detect a change in the underlying distribution. Such methods are widely used for industrial, medical, economical and other ... -
Screening-related prevalence and incidence for non-recurrent diseases
(University of Gothenburg, 1997-02-01)Expressions for prevalence (P) and incidence (I) in open dynamic populations are derived. When screenings are performed every s:th year, P and I will be functions of s. It is shown how the true values of P and l, which ... -
A stepwise regression procedure applied to an international production study - a multiple inference solution
(University of Gothenburg, 1997-04-01)The aim of this paper is to apply a certain procedure for stepwise regression analysis to a problem included in a study of integrated international production. The question, which factors are important for the transnational ... -

Multitype spatial point patterns with hierarchical interactions
(University of Gothenburg, 1998-01-01)Multitype spatial point patterns with hierarchical interactions are considered. Here hierarchical interaction means directionality: Points on a higher level of hierarchy affect the locations of points on the lower levels, ... -
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 ... -
Surveillance of spatial patterns - Change of interaction in the Ising model
(University of Gothenburg, 1998-03-01)Surveillance to detect changes of spatial patterns is of interest in many areas such as environmental control and regional analysis. Here the interaction parameter of the Ising model, is considered. A minimal sufficient ... -
Evaluation of some methods for statistical surveillance of an autoregressive process
(University of Gothenburg, 1998-04-01)Statistical surveillance is used for fast and secure detection of a critical event in a monitored process. This paper studies the performance for AR(l) processes. Two often suggested methods for detection of a shift in the ... -
On monitoring of environmental and other autoregressive processes
(University of Gothenburg, 1998-05-01)Statistical surveillance is used for monitoring a sequence of data arriving step by step. These techniques have been applied in many places in society and lately the interest and need for rational methods to be used on ... -
Barn som medforskare av matlandskap. Del 2: Meddesign
(2011-02)Denna rapport handlar om barn som ”co-designers” eller meddesigners. Den redovisar den metodik vi arbetat efter och de erfarenheter vi gjort inom ramen för projektet Barn som medforskare av matlandskap (BAMM). Projektet ...
