nosoi: A stochastic agent-based transmission chain simulation framework in r. [PDF]
Methods Ecol Evol, 2020 Abstract The transmission process of an infectious agent creates a connected chain of hosts linked by transmission events, known as a transmission chain. Reconstructing transmission chains remains a challenging endeavour, except in rare cases characterized by intense surveillance and epidemiological inquiry.

Clinical parameters predicting survival duration after hepatectomy for intrahepatic cholangiocarcinoma. [PDF]
Can J Gastroenterol, 2011 BACKGROUND: Currently, the most effective treatment for intrahepatic cholangiocarcinoma (ICC) is complete hepatic tumour excision. OBJECTIVE: To identify the clinical parameters associated with survival duration for ICC patients following hepatectomy, and to construct a mathematical model for predicting survival duration.

A Markov approach to credit rating migration conditional on economic states
Canadian Journal of Statistics, EarlyView.Abstract We develop a model for credit rating migration that accounts for the impact of economic state fluctuations on default probabilities. The joint process for the economic state and the rating is modelled as a time‐homogeneous Markov chain. While the rating process itself possesses the Markov property only under restrictive conditions, methods ...

Canadian Journal of Statistics, EarlyView.Abstract Intensity–duration–frequency curves are used by a wide range of professionals to manage the risks related to extreme rainfall. In Canada, these curves are produced by Environment and Climate Change Canada on the basis of Gumbel distributions fitted independently for each accumulation period.

Modélisation de la croissance de bovins : évolution des modèles et applications
INRAE Productions Animales, 2004 Les modèles mathématiques tiennent de nos jours une place importante dans les recherches en biologie. En productions animales, notamment dans le domaine de la croissance des bovins, de nombreux modèles ont été élaborés.

A goodness‐of‐fit test for regression models with discrete outcomes
Canadian Journal of Statistics, EarlyView.Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Mathematical Assessment of Canada’s Pandemic Influenza Preparedness Plan
Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 19, Issue 2, Page 185-192, 2008., 2008 OBJECTIVE: The presence of the highly pathogenic avian H5N1 virus in wild bird populations in several regions of the world, together with recurrent cases of H5N1 influenza arising primarily from direct contact with poultry, have highlighted the urgent need for prepared‐ness and coordinated global strategies to effectively combat a potential influenza ...

Cold hardiness mechanisms and modeling: existing approaches and future avenues
New Phytologist, Volume 249, Issue 6, Page 2668-2682, March 2026.Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.

Canadian Respiratory Journal, Volume 10, Issue 1, Page 27-34, 2003., 2003 There is no consensus on the methods to compare the clinical efficacy of different inhaled corticosteroids. A comparison needs to be made in terms of relative potency, and studies should include two‐, or preferably, three‐dose comparisons. A number of clinical models and outcomes are available; they have their relative advantages and disadvantages ...
