(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2013)We provide a notion of finite element system, that enables the construction spaces of differential forms, which can be used for the numerical solution of variationally posed partial difeerential equations. Within this ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Nested case-control and case-cohort studies are useful for studying associations between covariates and time-to-event when some covariates are expensive to measure. Full covariate information is collected in the nested ...
-
(Master thesis / Masteroppgave, 2011)In the last hundred years there have been a steady decline in mortality. When we are going to project how mortality is going to be in the future, we need a model who takes this decline in consideration. We have traditionally ...

(Research report / Forskningsrapport, 2005)Standard use of Cox's regression model and other relative risk regression models for censored survival data requires collection of covariate information on all individuals under study even when only a small fraction of ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Shapley values are today extensively used as a model-agnostic explanation framework to explain complex predictive machine learning models. Shapley values have desirable theoretical properties and a sound mathematical ...
-
(Master thesis / Masteroppgave, 2024)Our primary goal was to find analytic expressions for delta of option prices, where the underlying asset’s price is modeled with an exponential normal inverse Gaussian (NIG) process. We used the density method, starting ...

(Research report / Forskningsrapport, 2007)This paper introduces the concept of the utility copula, a function which incorporates the dependence information between (or among) variables of a utility function. A utility copula is a natural extension of the ordinary ...
