  • Bayesian sequential tests of the initial size of a linear pure death process 

    Goudie, I.B.J. (2015-05) - Journal article
    We provide a recursive algorithm for determining the sampling plans of invariant Bayesian sequential tests of the initial size of a linear pure death process of unknown rate. These tests compare favourably with the ...
  • Bayesian spatial NBDA for diffusion data with home-base coordinates 

    Nightingale, Glenna Faith; Laland, Kevin Neville; Hoppitt, William John Edward; Nightingale, Peter (2015-07-02) - Journal article
    Network-based diffusion analysis (NBDA) is a statistical method that allows the researcher to identify and quantify a social influence on the spread of behaviour through a population. Hitherto, NBDA analyses have not ...
  • Circular designs balanced for neighbours at distances one and two 

    Aldred, R. E. L.; Bailey, R. A.; Mckay, Brendan D.; Wanless, Ian M. (2014-12) - Journal article
    We define three types of neighbour-balanced designs for experiments where the units are arranged in a circle or single line in space or time. The designs are balanced with respect to neighbours at distance one and at ...

  • ‘A confession of ignorance’ : deaths from old age and deciphering cause-of-death statistics in Scotland, 1855–1949 

    Reid, A.; Garrett, E.; Dibben, C.; Williamson, L. (2015-02-11) - Journal article
    A large amount of the research undertaken in an attempt to discover the reasons underlying the late nineteenth- and early twentieth-century mortality decline in Britain has relied on the statistics published by the Registrars ...
  • Detectability in audio-visual surveys of tropical rainforest birds : the influence of species, weather and habitat characteristics 

    Anderson, Alexander S.; Marques, Tiago A.; Shoo, Luke P.; Williams, Stephen E. (2015-06-25) - Journal article
    Indices of relative abundance do not control for variation in detectability, which can bias density estimates such that ecological processes are difficult to infer. Distance sampling methods can be used to correct for ...
  • Distance sampling with a random scale detection function 

    Oedekoven, C.S.; Laake, J.L.; Skaug, H.J. (2015-12) - Journal article
    Distance sampling was developed to estimate wildlife abundance from observational surveys with uncertain detection in the search area. We present novel analysis methods for estimating detection probabilities that make use ...
  • Double bootstrap confidence intervals in the two-stage DEA approach 

    Chronopoulos, D.K.; Girardone, C.; Nankervis, J.C. (2015-09) - Journal article
    Contextual factors usually assume an important role in determining firms' productive efficiencies. Nevertheless, identifying them in a regression framework might be complicated. The problem arises from the efficiencies ...
  • Exploiting historical registers: Automatic methods for coding c19th and c20th cause of death descriptions to standard classifications 

    Carson, Jamie Kirk; Kirby, Graham Njal Cameron; Dearle, Alan; Williamson, Lee; Garrett, Eilidh; Reid, Alice; Dibben, Christopher John Lloyd (Eurostat, 2013-03-05) - Conference item
    The increasing availability of digitised registration records presents a significant opportunity for research. Returning to the original records allows researchers to classify descriptions, such as cause of death, to modern ...
  • From distance sampling to spatial capture-recapture 

    Borchers, David L.; Marques, Tiago A. (2017-01-10) - Journal article
    Distance sampling and capture–recapture are the two most widely used wildlife abundance estimation methods. capture–recapture methods have only recently incorporated models for spatial distribution and there is an increasing ...
  • General methods for evolutionary quantitative genetic inference from generalized mixed models 

    de Villemereuil, Pierre; Schielzeth, Holger; Nakagawa, Shinichi; Morrissey, Michael (2016-11-01) - Journal article
    Methods for inference and interpretation of evolutionary quantitative genetic parameters, and for prediction of the response to selection, are best developed for traits with normal distributions. Many traits of evolutionary ...
  • Growing through subsidies 

    Aloi, Marta; Lasselle, Laurence (School of Economics and Finance, University of St Andrews., 2001) - Working or discussion paper
    We consider an overlapping generation model based on Matsuyama (1999) and show that, whenever actual capital accumulation falls below its balanced growth path, subsidising innovators by taxing consumers has stabilising ...
  • Inter-annual and seasonal trends in cetacean distribution, density and abundance off southern California 

    Campbell, G.S.; Thomas, L.; Whitaker, K.; Douglas, A.B.; Calambokidis, J.; Hildebrand, J.A. (2015-02) - Journal article
    Trends in cetacean density and distribution off southern California were assessed through visual line-transect surveys during thirty-seven California Cooperative Oceanic Fisheries Investigations (CalCOFI) cruises from July ...
  • The modelling and assessment of whale-watching impacts 

    New, Leslie Frances; Hall, Ailsa Jane; Harcourt, R.; Kaufman, G.; Parsons, E.C.M.; Pearson, H.C.; Cosentino, A.M.; Schick, Robert Schilling (2015-10) - Journal article
    In recent years there has been significant interest in modelling cumulative effects and the population consequences of individual changes in cetacean behaviour and physiology due to disturbance. One potential source of ...
  • A non-technical overview of spatially explicit capture-recapture models 

    Borchers, David (2012-02) - Journal article
    Most capture-recapture studies are inherently spatial in nature, with capture probabilities depending on the location of traps relative to animals. The spatial component of the studies has until recently, however, not been ...
  • On optimality and construction of circular repeated-measurements designs 

    Bailey, Rosemary Anne; Cameron, Peter Jephson; Filipiak, Katarzyna; Kunert, Joachim; Markiewicz, Augustyn (2017-01) - Journal article
    The aim of this paper is to characterize and construct universally optimal designs among the class of circular repeated-measurements designs when the parameters do not permit balance for carry-over effects. It is shown ...
  • Optimal cross-over designs for full interaction models 

    Bailey, Rosemary Anne; Druilhet, Pierre (2014-11) - Journal article
    We consider repeated measurement designs when a residual or carry-over effect may be present in at most one later period. Since assuming an additive model may be unrealistic for some applications and leads to biased ...
  • Pairwise interaction point processes for modelling bivariate spatial point patterns in the presence of interaction uncertainty 

    Nightingale, Glenna Faith; Illian, Janine Baerbel; King, Ruth (2015-09) - Journal article
    Current ecological research seeks to understand the mechanisms that sustain biodiversity and allow a large number of species to coexist. Coexistence concerns inter-individual interactions. Consequently, there is an interest ...

    O'Hare, Bernadette Ann-Marie; Oladoyinbo, A.; Phiri, Grace (2009-05-01) - Journal article
    There is a paucity of information on inpatient paediatric units in Sub Saharan Africa and there tends only to be literature from larger countries such as South Africa. The aim of this paper is to give an overview of the ...
