    • Analyzing learning effects in the newsvendor model by probabilistic methods 

      Andersson, Jonas; Jörnsten, Kurt; Lillestøl, Jostein; Ubøe, Jan (Discussion paper;13/19, Working paper, 2019-10-11)
      In this paper, we use probabilistic methods to analyze learning effects in a behavioral experiment on the newsvendor model. We argue why we should believe that suggested orders follow a multinomial logit distribution, and ...

    • Bayesian estimation of NIG-parameters by Markov chain Monte Carlo methods 

      Lillestøl, Jostein (Discussion paper, Working paper, 2001-01)
      The Normal Inverse Gaussian (NIG) distribution recently introduced by Barndorff-Nielsen (1997) is a promising alternative for modelling financial data exhibiting skewness and fat tails. In this paper we explore the Bayesian ...

    • Benefit efficient statistical distributions on patient lists 

      Ubøe, Jan; Lillestøl, Jostein (Discussion paper, Working paper, 2006)
      In this paper we consider statistical distributions of different types of patients on the patient lists of doctors. In our framework different types of patients have different preferences regarding their preferred choice ...

    • Best estimate reporting with asymmetric loss 

      Lillestøl, Jostein; Sinding-Larsen, Richard (Discussion paper;07/15, Working paper, 2015-01-30)
      This paper considers the problem of point prediction based on a predictive distribution, representing the uncertainty about the outcome. The issue explored is the reporting of a single characteristic, typically the mean, ...

    • Beta-creaming 

      Lillestøl, Jostein; Sinding-Larsen, Richard (Discussion paper;08/15, Working paper, 2015-02-09)
      This paper considers sampling proportional to expected size from a partly unknown distribution. The applied context is the exploration for undiscovered resources, like oil accumulations in different deposits, where the ...

    • Beyond the local mean-variance analysis in continuous time. The problem of non-normality 

      Aase, Knut K.; Lillestøl, Jostein (Discussion paper;11/15, Working paper, 2015-02-23)
      The paper investigates the effects of deviations from normality on the estimates of risk premiums and the real equilibrium, short-term interest rate in the conventional rational expectations equilibrium model of Lucas ...

    • Cashier fraud : data analysis in a context 

      Lillestøl, Jostein (Discussion paper, Working paper, 1999)
      A true story is told about the role of a statistical expert witness in a cashier fraud case. It illustrates Shewhart’s first principle of understanding data: "Data have no meaning apart from their context". It may be used ...

    • Creaming - and the depletion of resources: A Bayesian data analysis 

      Lillestøl, Jostein; Sinding-Larsen, Richard (Discussion paper;16/17, Working paper, 2017-11-16)
      This paper considers sampling in proportion to size from a partly unknown distribution. The applied context is the exploration for undiscovered resources, like oil accumulations in different deposits, where the most promising ...

    • Driftspålitelighet : med statistikk som hjelper 

      Lillestøl, Jostein (Research report, 2000)

    • Fat and skew : can NIG cure? : on the prospects of using the normal inverse Gaussian distribution in finance 

      Lillestøl, Jostein (Discussion paper, Working paper, 1998-03)
      This paper explores the possibility of using the Normal Inverse Gaussian (NIG) distribution introduced by Barndorff-Nielsen (1997) in various problem areas in finance where distributions often are found to be non-normal ...

    • Functional data analysis : introduction and applications to financial electricity contracts 

      Lillestøl, Jostein; Ollmar, Fridthjof (Discussion paper, Working paper, 2003)

    • Hva vet vi om dem som skjuler inntekt og formue i skatteparadis? 

      Andersson, Jonas; Lillestøl, Jostein; Støve, Bård; Schjelderup, Guttorm (Journal article; Peer reviewed, 2013)
      I denne artikkelen presenteres resultater fra et prosjekt utført for SNF (Samfunns- og Næringslivsforskning) på oppdrag av Skattedirektoratet (SKD). Hensikten med prosjektet var å finne kjennetegn ved personlige skattytere ...

    • Kjennetegnsanalyser av skattytere som unndrar skatt ved å skjule formuer og inntekter i utlandet 

      Andersson, Jonas; Lillestøl, Jostein; Støve, Bård (Rapport;2012:10, Research report, 2012-09)
      I denne rapporten presenteres resultatet av et prosjekt utført for Skattedirektoratet (SKD). Hensikten har vært å finne kjennetegn ved personlige skattytere som har unndratt skatt gjennom å skjule formuer og/eller inntekt ...

    • Log-normal creaming and the likelihood of discovering additional giant petroleum fields 

      Lillestøl, Jostein; Sinding-Larsen, Richard (Discussion paper;3/16, Working paper, 2016-01-27)
      This paper considers sampling proportional to expected size from a partly unknown distribution. The applied context is the exploration for undiscovered resources, like oil accumulations in different deposits, where the ...

      Lillestøl, Jostein; Manne, Per (Discussion paper;23/23, Working paper, 2023-12-11)
      This paper examines some problems of matched dispatching in some different random settings. The context of presentation is that of a reality show with a lineup of the participants, and according to some probabilistic ...
