Baire category results for quasi–copulas
Dependence Modeling, 2016 The aim of this manuscript is to determine the relative size of several functions (copulas, quasi– copulas) that are commonly used in stochastic modeling.

Proportional Hazard Model and Proportional Odds Model under Dependent Truncated Data
Axioms, 2022 Truncation data arise when the interested event time can be observed only if it satisfies a certain condition. Most of the existing approaches analyze this kind of data by assuming the truncated variable is quasi-independent of the interested event time.

On the Size of Subclasses of Quasi-Copulas and Their Dedekind–MacNeille Completion
Mathematics, 2020 We study some topological properties of the class of supermodular n-quasi-copulas and check that the topological size of the Dedekind–MacNeille completion of the set of n-copulas is small, in terms of the Baire category, in the Dedekind–MacNeille ...

Quasi-Copulas, Copulas and Fuzzy Implicators
International Journal of Computational Intelligence Systems, 2020 In this paper, we study relations between fuzzy implicators and some kinds of fuzzy conjunctors, in particular, quasi-copulas and copulas. We show that there is a one-to-one correspondence between the classes of all quasi-copulas and 1-Lipschitz fuzzy ...

Quadratic transformation of multivariate aggregation functions
Dependence Modeling, 2020 In this work, we prove that quadratic transformations of aggregation functions must come from quadratic aggregation functions. We also show that this is different from quadratic transformations of (multivariate) semi-copulas and quasi-copulas.

Characterizations of multivariate quasi-copulas(多元拟连接函数的刻画)
Zhejiang Daxue xuebao. Lixue ban, 2007 CENEST等曾给出二元拟连接函数的两个等价刻画，同时提出一问题：引理可否推广到高维？本文回答了这一问题，证明了引理在高维时也是成立的；并指出其中一个刻画可以推广到多元，作为多元拟连接函数的刻画，而另一个刻画在高维时不成立；最后进一步得到多元线性拟连接函数概念，它是多元拟连接函数的推广.

Dependence Modeling, 2013 Nelsen et al. [20] find bounds for bivariate distribution functions when there are constraints on the values of its quartiles. Tankov [25] generalizes this work by giving explicit expressions for the best upper and lower bounds for a bivariate copula ...

Functionally Constructed Semi Linear Copulas from Fuzzy Implication Operators
AxiomsThis paper proposes a framework for generating symmetric two-branched copulas directly from fuzzy implications via monotone function composition. The proposed approach is based on a two-branched composition principle induced by fuzzy implications and ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how digital strategic orientation (DSO) and environmental practices (EP) interact to shape innovation and performance among Chilean SMEs. Using survey data from 271 firms (February–May 2022), we estimate a generalized structured component analysis (GSCA) model that accommodates a nonrecursive relationship between DSO and EP.

Business Strategy and the Environment, EarlyView.ABSTRACT Although prior studies show that overall product environmental sustainability enhances consumer value perceptions, it remains unclear how consumers interpret environmental sustainability signals across phases of the life cycle assessment process.
