  Background: The heritability of traits such as body mass index (BMI), a measure of obesity, is generally estimated using family and twin studies, and increasingly by molecular genetic approaches. These studies generally ...

• On stochastic control for time changed Lévy dynamics 

  Di Nunno, Giulia (Peer reviewed; Journal article, 2022)

  Controlled stochastic differential equations driven by time changed Lévy noises do not enjoy the Markov property in general, but can be treated in the framework of general martingales. From the modelling point of view, ...

• Statistical dependence: Beyond Pearson’s ρ 

  Tjøstheim, Dag Bjarne; Otneim, Håkon; Støve, Bård (Peer reviewed; Journal article, 2022)

  Pearson’s ρ is the most used measure of statistical dependence. It gives a complete characterization of dependence in the Gaussian case, and it also works well in some non-Gaussian situations. It is well known, however, ...

• Local Lead–Lag Relationships and Nonlinear Granger Causality: An Empirical Analysis 

  Otneim, Håkon; Berentsen, Geir Drage; Tjøstheim, Dag Bjarne (Peer reviewed; Journal article, 2022)

  The Granger causality test is essential for detecting lead–lag relationships between time series. Traditionally, one uses a linear version of the test, essentially based on a linear time series regression, itself being ...

• Drift-implicit Euler scheme for sandwiched processes driven by Hölder noises 

  Di Nunno, Giulia; Mishura, Yuliya; Yurchenko-Tytarenko, Anton (Peer reviewed; Journal article, 2022)

• Who benefits from postponement in multi-period supply channel optimization? 

  Azad Gholami, Reza; Sandal, Leif Kristoffer; Ubøe, Jan (Peer reviewed; Journal article, 2023)

  Duopolistic price-setting supply channels competing in a bilevel framework have been extensively studied in single-period (static) settings. However, such supply channels typically face uncertain and time-varying demand; ...

• Balanced Scorecards: A Relational Contract Approach 

  Kvaløy, Ola; Olsen, Trond Egil (Peer reviewed; Journal article, 2022)

  Reward systems based on balanced scorecards often connect pay to an index, i.e. a weighted sum of multiple performance measures. We show that such an index contract may indeed be optimal if performance measures are ...

• Construction of Equilibria in Strategic Stackelberg Games in Multi-Period Supply Chain Contracts 

  Azad Gholami, Reza; Sandal, Leif Kristoffer; Ubøe, Jan (Peer reviewed; Journal article, 2022)

  Almost every supplier faces uncertain and time-varying demand. E-commerce and online shopping have given suppliers unprecedented access to data on customers’ behavior, which sheds light on demand uncertainty. The main ...

• Multidisciplinary perspectives on living marine resources in the Arctic 

  Kvamsdal, Sturla Furunes; Dankel, Dorothy Jane; Ekerhovd, Nils-Arne; Hoel, Alf Håkon; Renner, Angelika; Sandø, Anne Britt; Steinshamn, Stein Ivar (Peer reviewed; Journal article, 2022)

  Many areas in the Arctic are vulnerable to the impacts of climate change. We observe large-scale effects on physical, biological, economic and social parameters, including ice cover, species distributions, economic activity ...

• Poleward spawning of Atlantic mackerel (Scomber scombrus) is facilitated by ocean warming but triggered by energetic constraints
