Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP

Canadian Journal of Statistics, EarlyView.
Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

Canadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Text mining methods: an answer to Chartier and Meunier [PDF]

, 2001
Almost 20 years ago, in a paper introducing the text mining (TM) technique to my fellow statisticians, I expressed the fear that: “it would be unfortunate that this technique, because it is apparently so easy to use, would be abused by incompetent ...

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

De Cambridge para o mundo, historicamente: revendo a contribuição metodológica de Quentin Skinner

Dados: Revista de Ciências Sociais, 2005
Dans cet article, on souligne un problème central de l'approche méthodologique de Quentin Skinner concernant l'étude de l'histoire de la pensée politique: l'équivalence adoptée par l'auteur entre la communication orale et la communication écrite.

Audit Quality From a Service Perspective: A Systematic Literature Review

Accounting Perspectives, EarlyView.
ABSTRACT Audit quality is a multidimensional and latent construct that researchers struggle to evaluate and interpret. This paper follows an interdisciplinary approach by systematically reviewing the literature on audit quality evaluation from a service quality perspective.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

New options for pest management in horticultural crop-based agroecosystems of Sudano-Sahelian Africa in the climate change context [PDF]

, 2011
In the climate change context, ICRISAT is promoting water-saving cropping systems mixing food and horticultural crops for the Sudano-Sahelian zone of Western Africa. ICRISAT's partners in Niger (CIRAD, the University of Niamey and INRAN) are seeking ways

Establishment and validation of a hair fall atlas for Chinese men based on trichoscopy

International Journal of Cosmetic Science, EarlyView.
A new hair fall atlas with 7 scales is established and validated and ready to publish as a new methodology. We observed good consistency between the dermatologists' grading (PCC >0.8), and a strong correlation shown between clinical scores and hair fall attributes based on image analysis (|p| > 0.8).
