  • Optimal Bayesian sampling acceptance plan with random censoring 
    Choy, S.; Chen, J.; Li, K. (Elsevier Science, 2007)
    The sampling acceptance scheme with censoring is one of the important life inspection problems. In this article, a general model of sampling acceptance plan for the exponential distribution with exponentially distributed ...
  • Optimal designs for 2(k) choice experiments 
    Street Deborah; Burgess Leonie (Oxford University Press, 2002)
    In this article we establish the choice sets in the D-optimal design for a choice experiment for testing main effects and for testing main effects and two-factor interactions. when there are k attributes. each with two ...
  • Optimal Designs for 2k Paired Comparison Experiments 
    Bunch David; Street Deborah; Moore Beverley (Nature Publishing Group, 2005)
    In this paper we establish the form of the optimal paired comparison design when there are k attributes, each with two levels, for testing for main effects, for main effects and two factor interactions and for main ...
  • Optimal designs for choice experiments with asymmetric attributes 
    Street Deborah; Burgess Leonie (Elsevier Science, 2003)
    In this paper we establish the form of the optimal design for choice experiments in which attributes need not have the same number of levels for testing main effects only, when there are k attributes, and all choice sets ...
  • Optimal designs for stated choice experiments that incorporate position effects 
    Bush Stephen; Street Deborah; Burgess Leonie (Marcel Dekker, 2012)
    Davidson and Beaver (1977) extended the Bradley-Terry model to incorporate the possible effect of position within a choice set on the choices made in paired comparisons experiments. We further extend the Davidson-Beaver ...
  • Optimal designs for stated choice experiments that incorporate ties 
    Bush Stephen; Burgess Leonie; Street Deborah (Elsevier Inc, 2010)
    In 1970 Davidson generalised the Bradley-Terry model to allow respondents to say that the two options presented in a choice task were equally attractive. In this paper we extend this idea to the MNL model with m options ...
  • Optimal location of Tsunami warning buoys and sea level monitoring stations in the Mediterranean Sea 
    Groen Layna; Joseph Anthony; Black Eileen; Menictas Marianne; Tam Winsom; Gabor Matthew (Tsunami Society International, 2010)
    The present study determines the optimal location of detection components of a tsunami warning system in the Mediterranean region given the existing and planned infrastructure. Specifically, we examine the locations of ...
  • Optimal Models with Maximizing the Probability of First Achieving Target Value in the Preceding Stages 
    Lin Yuanlie; Wu Congbin; Kang Boda (Zhongguo Kexue Zazhishe, 2003)
    Decision makers often face the need of performance guarantee with some sufficiently high probability. Such problems can be modelled using a discrete time Markov decision process (MDP) with a probability criterion for the ...
  • Optimal Processes in Irreversible Microeconomics 
    Tsirlin Anatoly; Kazakov Vladimir (Nova, 2007)
    In this paper we consider optimal trading processes in economic systems. The analysis is based on accounting for irreversibility factor using wealth function concept.
  • The optimal size of choice sets in choice experiments 
    Burgess Leonie; Street Deborah (Triangle Journals, 2002)
    In this paper, we establish the optimal size of the choice sets in generic choice experiments for asymmetric attributes when estimating main efects only. We give an upper bound for the determinant of the information ...
  • Optimal stated preference choice experiments when all choice sets contain a specific option 
    Burgess Leonie; Street Deborah (Elsevier, 2007)
    Stated preference choice experiments are routinely used in many areas from marketing to medicine. While results on the optimal choice sets to present for the forced choice setting have been determined in a variety of ...
  • Optimising the location of tsunami detector buoys and sea-level monitors in the Indian Ocean 
    Groen Layna; Botten Lindsay; Blazek Katerina (Inderscience, 2010)
    In the wake of the 2004 Boxing Day tsunami disaster, a global response to implement a tsunami warning system in the Indian Ocean became imperative. Steps in this direction were initiated in 2005 with plans for the deployment ...
  • Parameter-dependent H infinity Control for Time-varying Delay Polytopic Systems 
    Phat V; Ha Quang; Trinh H (Springer Science+Business Media, 2010)
    This paper addresses the robust stabilization and H infinity control problem for a class of linear polytopic systems with continuously distributed delays. The control objective is to design a robust H infinity controller ...
  • Parsimonious classification via generalised linear mixed models 
    Kauermann G.; Ormerod John; Wand Matt (Springer New York LLC, 2010)
    We devise a classification algorithm based on generalized linear mixed model (GLMM) technology. The algorithm incorporates spline smoothing, additive model-type structures and model selection. For reasons of speed we employ ...
  • Particle swarm optimization for bi-level pricing problems in supply chains 
    Gao Ya; Zhang Guangquan; Lu Jie; Wee Hui-Ming (Springer New York LLC, 2011)
    With rapid technological innovation and strong competition in hi-tech industries such as computer and communication organizations, the upstream component price and the downstream product cost usually decline significantly ...
  • Penalised spline support vector classifiers: computational issues 
    Ormerod John; Wand Matt; Koch Inge (Physica-Verlag Gmbh & Co, 2008)
    We study computational issues for support vector classification with penalised spline kernels. We show that, compared with traditional kernels, computational times can be drastically reduced in large problems making such ...
  • Penalized splines and reproducing kernel methods 
    Pearce N.; Wand Matt (American Statistical Association, 2006)
    Two data analytic research areas¿penalized splines and reproducing kernel methods¿have become very vibrant since the mid-1990s. This article shows how the former can be embedded in the latter via theory for reproducing ...
  • Penalized wavelets: Embedding wavelets into semiparametric regression 
    Wand Matthew; Ormerod John (Institute of Mathematical Statistics, 2011)
    We introduce the concept of penalized wavelets to facilitate seamless embedding of wavelets into semiparametric regression models. In particular, we show that penalized wavelets are analogous to penalized splines; the ...
