We introduce a novel ensemble learning approach which combines random partitions models through Potts clustering with a non-parametric predictor such as sha...

In this paper we consider a differentiated oligopoly with two product varieties that are supplied by two groups of firms. We assume that firms can change t...

We analyze a differential game with spatially distributed controls to study a multiregional transboundary pollution problem. The dynamics of the state variab...

Very large networks linking dynamical agents are now ubiquitous and the need to analyse, design and control them is evident. The emergence of the graphon the...

In this study, we develop a deterministic nonlinear filtering algorithm based on a high-dimensional version of Kitagawa (1987) to evaluate the likelihood fun...

Les organismes caritatifs jouent un rôle important dans la production de biens et services. L'objectif de cet article est de déterminer la politique optimale...

We analyze an endogenous growth model with non-constant discounting and a negative externality of growth on utility. With a decreasing rate of impatience, ...

Drawing on statistical learning theory, we derive out-of-sample and optimality guarantees about the investment strategy obtained from a regularized portfoli...

référence BibTeX

We consider several time series and for each of them, we fit an appropriate dynamic parametric model. This produces serially independent error terms for each...

For nearest neighbor univariate random walks in a periodic environment, where the probability of moving depends on a periodic function, we show how to estim...

Given \(n\) points, a symmetric dissimilarity matrix \(D\) of dimensions \(n\times n\) and an integer \(p\geq 2\), the \(p\)-dispersion problem (pD...

Operations Research (OR) has a very important role to play in credit scoring for building models that can help the lending organization to make a good decisi...

In this paper, we propose an intuitive way to couple several dynamic time series models even when there are no innovations. This extends previous work for m...

Dans le cadre de sa réforme du processus d’insolvabilité aux États-Unis, l’American Bankruptcy Institute (ABI) propose l’octroi d’une option de remboursement...

In this paper, we consider non-stationary response variables and covariates, where the marginal distributions and the associated copula may be time-dependent...

Generally, the semiclosed-form option pricing formula for complex financial models depends on unobservable factors such as stochastic volatility and jump int...

Dans le cadre du calcul du risque de contrepartie, le risque de corrélation réfère à une situation où la valeur d'une transaction financière est corrélée av...

À la suite de la crise financière de 2007, la réforme de Bâle III recommande, entre autres, la mise en place de frais de capital couvrant la variabilité de ...

We analyze a transboundary pollution differential game where, in addition to the standard temporal dimension, a spatial dimension is introduced to capture th...

Le paradoxe de Parrondo est étendu à des marches aléatoires en environnements aléatoires avec changement de régimes. Le comportement paradoxal de la march...
