(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Statistical prediction methods typically require some form of fine‐tuning of tuning parameter(s), with K‐fold cross‐validation as the canonical procedure. For ridge regression, there exist numerous procedures, but common ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In this paper, we present a comprehensive survey of continuous stochastic volatility models, discussing their historical development and the key stylized facts that have driven the field. Special attention is dedicated to ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The correlation of different methods of measurement can become an important tool to identify the dominant physical elements that govern the electronic and ionic dynamics in perovskite solar cells. The diverse phenomena ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)It has recently been demonstrated (Frauendiener and Hennig 2014 Class. Quantum Grav. 31 085010) that the conformally invariant wave equation on a Minkowski background can be solved with a fully pseudospectral numerical ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)The seller’s risk-indifference price evaluation is studied. We propose a dynamic risk-indifference pricing criteria derived from a fully- dynamic family of risk measures on the L_p-spaces for p ∈ [1, ∞]. The concept of ...

-
(Master thesis / Masteroppgave, 2020)The aim of this thesis is twofold. First we introduce a Hilbert-valued multi-market two-factor forward curve model satisfying the Heath-Jarrow-Morton equation. Each forward curve consist of a shared source of noise and a ...

(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2018)We investigate the relative computational strength of combinations of four higher order functionals, the jump and hyperjump seen as functionals of type 2 and realisers for the compactness of Cantor space and the Lindelöf ...
