Coupling physical understanding and statistical modeling to estimate ice jam flood frequency in the northern Peace-Athabasca Delta under climate change
This study contributes to this debate by addressing two questions: (1) what factors are most predictive of Peace River IJFs, and (2) how might climate change impact IJF frequency?
APPLICATIONS
Computing Accurate Probabilistic Estimates of One-D Entropy from Equiprobable Random Samples
Results indicate, for the class of distributions tested, that the optimal number of quantile-spacings is a fixed fraction of the sample size (empirically determined to be ~0. 25-0. 35), and that this value is relatively insensitive to distributional form or sample size, providing a clear advantage over BC since hyperparameter tuning is not required.

Accounting for recall bias in case-control studies: a causal inference approach
A case-control study is designed to help determine if an exposure is associated with an outcome.
METHODOLOGY APPLICATIONS
Assessing the causal effects of a stochastic intervention in time series data: Are heat alerts effective in preventing deaths and hospitalizations?
To overcome this challenge, first we introduce a new class of causal estimands under a stochastic intervention (i. e., increasing the odds of issuing a heat alert) for a single time series corresponding to a given location.

Confidently Comparing Estimators with the c-value
• blt2114/c_values
• 
In response, we propose the "c-value" as a measure of confidence that a new estimate achieves smaller loss than an old estimate on a given dataset.

hesim: Health Economic Simulation Modeling and Decision Analysis
Health economic models simulate the costs and effects of health technologies for use in health technology assessment (HTA) to inform efficient use of scarce resources.
APPLICATIONS
Stochastic Convergence Rates and Applications of Adaptive Quadrature in Bayesian Inference
We provide the first stochastic convergence rates for adaptive Gauss--Hermite quadrature applied to normalizing the posterior distribution in Bayesian models.
METHODOLOGY
Continuum centroid classifier for functional data
Thanks to the intrinsic infinite dimension of functional data, one of two subtypes of CCC enjoys the (asymptotic) zero misclassification rate.
