A class of directed acyclic graphs with mixed data types in mediation analysis
Canadian Journal of Statistics, EarlyView.Abstract We propose a unified class of generalized structural equation models (GSEMs) with data of mixed types in mediation analysis, including continuous, categorical, and count variables. Such models extend substantially the classical linear structural equation model to accommodate many data types arising from the application of mediation analysis ...

A probabilistic diagnostic for Laplace approximations: Introduction and experimentation
Canadian Journal of Statistics, EarlyView.Abstract Many models require integrals of high‐dimensional functions: for instance, to obtain marginal likelihoods. Such integrals may be intractable, or too expensive to compute numerically. Instead, we can use the Laplace approximation (LA). The LA is exact if the function is proportional to a normal density; its effectiveness therefore depends on ...

Hydrologic Drought Frequency Analysis in Karkhe Basin Based on Bivariate Statistical Analysis
علوم آب و خاک, 2018 In recent years, the joint distribution properties of drought including severity and duration have been widely evaluated using copula. Few studies, however, have worked on drought modeling based on stream flow, especially in semi-arid regions such as the

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT There is growing demand for environmental sustainability in fashion supply chains (FSC), particularly to face risks related to climate change and pollution of suppliers in developing nations. Hence, supply chain (SC) actors must reconcile environmental sustainability from two perspectives: waste management and pollution/emissions.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This paper contributes to the literature by being a pioneer in investigating the role of independent directors in influencing ESG controversies in European firms, examining CSR strategy as a mediating mechanism. Using data from STOXX Europe 600 Index listed companies from 2007 to 2023, the results reveal that while independent directors ...
