A straightforward analytical calculation of the distribution of an annuity certain with stochastic interest rate.
No full textStarting from the moment generating function of the annuity certain with stochastic interest rate written by means of a time discretization of the Wiener process as an n-fold integral, a straightforward evaluation of the corresponding distribution function is obtained letting n tend to infinity. The advantage of the present method consists in the direct calculation technique of the n-fold integral, instead of using moment calculation or differential equations, and in the possible applicability of the present method to varying annuities which could be applied to IBNR results, as well as to pension fund calculations, etc.Distribution; Annuities; Processes; Evaluation;

Hoort lumbale MRI thuis in de eerste lijn?
No full textDe Schepper E. Usefulness of lumbar MRI in general practice. Huisarts Wet 2017;60(1):21-3. General practitioners (GPs) in the Netherlands can now refer patients for MRI of the lumbar spine, but as yet there are no data on its use. For this reason, this cohort study investigated the use of lumbar MRI by Dutch GPs. One of the most striking findings was that at the time of referral most patients had had lasting symptoms and complaints for a long time. Furthermore, the MRI reports indicated that there were a relatively high number of disc pathologies. The MRI findings did not influence the GP’s decision to refer a patient to a specialist or the prognosis regarding recovery. From a clinical perspective, these results raise a number of questions about the usefulness of lumbar MRI in general practice. In order to establish whether MRI of the lumbar spine should be used as diagnostic instrument in primary care or restricted to secondary care, a well-designed randomized trial of diagnostic accuracy and cost-effectiveness is required. Until then, GPs are advised to follow the recommendations of the relevant Dutch College of General Practitioner’s guideline, which advises against diagnostic imaging in primary care
Transition probabilities for diffusion equations by means of path integrals.
No full textIn this paper, we investigate the transition probabilities for diffusion processes. In a first part, we show how transition probabilities for rather general diffusion processes can always be expressed by means of a path integral. For several classical models, an exact calculation is possible, leading to analytical expressions for the transition probabilities and for the maximum probability paths. A second part consists of the derivation of an analytical approximation for the transition probability, which is useful in case the path integral is too complex to be calculated. The approximation we present is based on a convex combination of a new analytical upper and lower bound for the transition probabilities. The fact that the approximation is analytical has some important advantages, e.g. for the investigation of Asian options. Finally, we demonstrate the accuracy of the approximation by means of a few graphical illustrationsAdvantages; Comonotonicity; Diffusion processes; Models; Option; Path integral;
Stochastic approximations of present value functions.
No full textThe aim of the paper is to apply the method proposed by Denuit, Genest and Marceau (1999) for deriving stochastic upper and lower bounds on the present value of a sequence of cash flows, where the discounting is performed under a given stochastic return process. The convex approximation provided by Goovaerts, Dhaene and De Schepper (1999) and Goovaerts and Dhaene (1999) is then compared to these stochastic bounds. On the basis of several numerical examples, it will be seen that the convex approximation seems reasonable.Value; Functions;
A matrix Hilbert transform in Hermitean Clifford analysis
No full textAbstractOrthogonal Clifford analysis is a higher dimensional function theory offering both a generalization of complex analysis in the plane and a refinement of classical harmonic analysis. During the last years, Hermitean Clifford analysis has emerged as a new and successful branch of it, offering yet a refinement of the orthogonal case. Recently in [F. Brackx, B. De Knock, H. De Schepper, D. Peña Peña, F. Sommen, submitted for publication], a Hermitean Cauchy integral was constructed in the framework of circulant (2×2) matrix functions. In the present paper, a new Hermitean Hilbert transform is introduced, arising naturally as part of the non-tangential boundary limits of that Hermitean Cauchy integral. The resulting matrix operator is shown to satisfy properly adapted analogues of the characteristic properties of the Hilbert transform in classical analysis and orthogonal Clifford analysis
A finite element method for elliptic eigenvalue problems in a multi-component domain in 2D with non-local Dirichlet transition conditions.
No full textAbstractIn this paper we consider a class of eigenvalue problems (EVPs) on a bounded multi-component domain in the plane, which consists of a number of convex polygonal subdomains. On the outer boundaries classical mixed Robin–Dirichlet conditions hold, while we impose nonlocal transition conditions (TCs) of Dirichlet-type on the interfaces between two subdomains. First, we state the variational formulation of this problem. This variational EVP then serves as the starting point for internal approximation methods such as finite element methods (FEMs), developed here. The error analysis involved mainly rests upon the properties of a deliberately defined imperfect Lagrange interpolant. Considerable attention is also paid to a crucial density result and to the computational aspects. This paper extends the results of De Schepper and Van Keer (Numer. Funct. Anal. Optim. 19 (9&10) (1998)), where the finite element analysis was restricted to the case of a rectangle consisting of four rectangular subdomains. Finally, the analysis is illustrated by a numerical example
