Permutation Tests Based on the Copula‐Graphic Estimator and Their Use for Survival Tree Construction
Statistics in Medicine, Volume 45, Issue 6-7, March 2026.ABSTRACT Survival trees are popular alternatives to Cox or Aalen regression models that offer both modeling flexibility and graphical interpretability. This paper introduces a new algorithm for survival trees that relaxes the assumption of independent censoring. To this end, we use the copula‐graphic estimator to estimate survival functions.

Market Insurance and Risk Pooling in U.S. Crop Insurance
Agricultural Economics, Volume 57, Issue 2, March 2026.ABSTRACT A common assumption is that multiple‐peril crop insurance markets suffer from market failures, thus justifying government intervention in the form of premium subsidies, operating allowances, and reinsurance agreements. One prominent rationale for intervention involves geographic correlation in agricultural production which leads to systemic ...

McDowell and Sellars on Objective Purport
European Journal of Philosophy, Volume 34, Issue 1, Page 313-332, March 2026.Abstract John McDowell has criticized Wilfrid Sellars on several occasions and over a number of years for his ‘non‐relational’ account of intentionality. This account is, according to McDowell, at least partly responsible for a ‘blind spot’ in Sellars's thinking: Sellars, allegedly, fails to see how objects or states of affairs in the external world ...

Epistemological Implications of a System—Theoretical Understanding for Sustainability Models
Systems Research and Behavioral Science, Volume 43, Issue 1, Page 96-110, January/February 2026.ABSTRACT In the sense of the Sustainable Development Goals (SDGs), global efforts to create a sustainable society will not be sufficiently successful under the current geopolitical and socio‐economic trends. For this reason, recent sustainability research has increasingly focused on systemic coherence, the subject of cognition, and psychological and ...

On approximating copulas by finite mixtures
, 2018 Copulas are now frequently used to approximate or estimate multivariate distributions because of their ability to take into account the multivariate dependence of the variables while controlling the approximation properties of the marginal densities ...

This paper considers the linear objective function optimization with respect to a more general class of bipolar fuzzy relational equations, where the fuzzy compositions are defined by an arbitrary continuous Archimedean t-norm. In addition, a faster method for finding a global optimum is proposed.
