An Application of Machine Learning and Textual Analytics for Visualisation and Enhanced Interpretation of Sustainability Disclosure

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Social and environmental accounting provides accountability mechanisms through which organisations communicate their sustainability practices to stakeholders. However, the increasing volume, complexity and diversity of sustainability disclosures make manual content analysis both labour‐intensive and susceptible to subjectivity.

Dirichlet process probit misclassification mixture model for misclassified binary data [PDF]

open access: yes, 2021
Mislabelling or misclassification in binary data refers to incorrectly labelled responses and could arise due to problems in the labelling process or imperfect evidence for labelling.

Greenwashing or Sustainability Misalignment? Analysing Organisational, Workplace and Real Estate Strategies Through an Iceberg Lens

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Environmental sustainability and the broader Environmental, Social and Governance (ESG) agenda have become prominently proclaimed organisational priorities, yet their integration into core decision‐making remains uneven. While greenwashing research has largely focused on communication and disclosure, it has paid less attention to the internal ...

Producing power-law distributions and damping word frequencies with two-stage language models [PDF]

open access: yes, 2011
Standard statistical models of language fail to capture one of the most striking properties of natural languages: the power-law distribution in the frequencies of word tokens.

Bayesian correlated clustering to integrate multiple datasets [PDF]

open access: yes, 2012
Motivation: The integration of multiple datasets remains a key challenge in systems biology and genomic medicine. Modern high-throughput technologies generate a broad array of different data types, providing distinct – but often complementary ...

Large parameter asymptotic analysis for homogeneous normalized random measures with independent increments

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Homogeneous normalized random measures with independent increments represent a broad class of Bayesian nonparametric priors and thus are widely used. In this article, we obtain the strong law of large numbers, the central limit theorem (CLT), and the functional central limit theorem (fCLT) of such measures when the concentration parameter a ...

Mitigating measurement error in misspecified small area models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract In the framework of Small area estimation, we consider an area‐level model where a subset of covariates is measured with error. The extent of the error is assumed to be constant throughout the areas, and it is expressed by a scalar parameter γ$$ \gamma $$, which multiplies the deterministic covariance matrix of the estimator of the true ...

From Dictionaries to Deep Learning: A Systematic Mapping Review of the Natural Language Processing Tasks Used to Analyze Sustainability Reports

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study aims at shedding light on the vast landscape of natural language processing (NLP) tasks used when analyzing sustainability reports or sustainability within integrated annual reports. A systematic literature review is carried out, identifying 160 studies of relevance.

Spike-and-Slab Dirichlet Process Mixture Models

open access: yesOpen Journal of Statistics, 2012
In this paper, Spike-and-Slab Dirichlet Process (SS-DP) priors are introduced and discussed for non-parametric Bayesian modeling and inference, especially in the mixture models context. Specifying a spike-and-slab base measure for DP priors combines the merits of Dirichlet process and spike-and-slab priors and serves as a flexible approach in Bayesian ...

A semiparametric Bayesian approach to the analysis of financial time series with applications to value at risk estimation [PDF]

open access: yes
Financial time series analysis deals with the understanding of data collected on financial markets. Several parametric distribution models have been entertained for describing, estimating and predicting the dynamics of financial time series ...
