Welcome to the Department of Statistics and Actuarial Science

The Department of Statistics and Actuarial Science is among the top academic units for statistical and actuarial science in the world and is home to more than 40 research active full-time faculty working in diverse and exciting areas. The Department is also home to over 900 undergraduate students and about 150 graduate students in programs including Actuarial Science, Biostatistics, Quantitative Finance, Statistics, and Statistics-Computing.

We are located on University of Waterloo main campus, which is located at the heart of Canada's Technology Triangle about 100 kilometers west of Toronto.

    Recurrent Marker Processes in the Presence of Competing Terminal Events

    In follow-up studies, utility marker measurements are usually collected upon the occurrence of recurrent events until a terminal event such as death takes place. In this talk, we define the recurrent marker process to characterize utility accumulation over time. For example, with medical cost and repeated hospitalizations being treated as marker and recurrent events respectively, the recurrent marker process is the trajectory of cumulative medical cost, which stops to increase after death.

    Constraints, Priors and Bayesian Computation

    In statistical modelling, constraints can be broadly defined as any restriction over the statistical model or its parameters that create inferential or computational challenges and require special treatment. In the first part of this presentation, a variant of the sequential Monte Carlo sampler -- referred to as Sequentially Constrained Monte Carlo (SCMC)-- is introduced to address efficient sampling from a target distribution in presence of constraints.

    High-dimensional Generalizations of Asymmetric Least Squares and Their Applications

    Asymmetric least squares (ALS) regression is a convenient and effective method of summarizing the conditional distribution of a response variable given the covariates. Recent years have seen a growing interest in ALS amongst statisticians, econometricians and financial analysts. However, existing work on ALS only considers the traditional low-dimension-and-large-sample setting.
