Evaluating the impact of items and cooperation in inventory models with exemptable ordering costs
(Elsevier B.V., 2024-03)
[Absctract]: In this paper we introduce and analyse, from a game theoretical perspective, several multi-agent or multi-item continuous review inventory models in which the buyers are exempted from ordering costs if the ...
Cost-sensitive thresholding over a two-dimensional decision region for fraud detection
(Elsevier B.V., 2024-02)
[Absctract]: Credit fraud poses a challenging task in terms of detection. It can result in significant losses depending on the amount, so a cost-sensitive perspective needs to be taken. Classical approaches focus on ...
Probability of default estimation in credit risk using mixture cure models
(Elsevier, 2024-01)
[Abstract]: An estimator of the probability of default (PD) in credit risk is proposed. It is derived from a nonparametric conditional survival function estimator based on cure models. Asymptotic expressions for the bias ...
Analyzing categorical time series with the R package ctsfeatures
(Elsevier B.V., 2024-03)
[Absctract]: Time series data are ubiquitous nowadays. Whereas most of the literature on the topic deals with real-valued time series, categorical time series have received much less attention. However, the development of ...
A Nonparametric Bootstrap Method for Heteroscedastic Functional Data
(Springer, 2024-03)
[Absctract]: The objective is to provide a nonparametric bootstrap method for functional data that consists of independent realizations of a continuous one-dimensional process. The process is assumed to be nonstationary, ...
