Prerequisite: DATA 311, and fourth-year standing in the Data Science major or honours program.
STAT 401 (3) Probability and Statistical Inference
Formal introduction to the theory of statistical modelling with a focus on distributions of data, likelihood based inference for learning unknown parameters, construction of confidence intervals and development of tests. Bayesian methods will be used to contrast standard statistical procedures. Credit will be granted for only one of STAT 309 or STAT 401. [3-1-0]
Prerequisite: All of STAT 230, STAT 303.
STAT 403 (3) Stochastic Processes
Random walks, Markov chains, Poisson processes, continuous time Markov chains, birth and death processes, exponential models, and applications of Markov chains. [3-0-0]
Prerequisite: STAT 303.
STAT 406 (3) Environmetrics
Foundation of the use of statistical concepts and methods in environmental science and management. Scientific problem-solving using statistical methods. Integration of the formulation of objectives, study design, and quantitative methods appropriate for the design. The role and use of statistical software packages. [3-0-0]
Prerequisite: STAT 230.
STAT 448 (3/6) d Directed Studies in Statistics
Investigation of a specific topic as agreed upon by the student and the faculty supervisor. Completion of a project and an oral presentation are required. No more than 6 credits of STAT 448 may be taken for credit.
Prerequisite: Successful completion of 15 credits of 300- or 400-level MATH and STAT courses; and permission of the department head and faculty supervisor.
STAT 449 (3-9) d Special Topics in Statistics
Students should consult with the unit to determine the availability of specific topics to be offered under the direction of a staff member. May be taken more than once with different topics.
Prerequisite: Permission of the department head.
STAT 507 (3) Sampling and Design
Collection of data using either designed experiments or survey samples. Planning and practice of data collection. Observational and experimental data pros and cons. Standard methods in survey samples. Experimental design review. Credit will be granted for only one of DATA 407, STAT 405, STAT 407 or STAT 507.
STAT 538 (3) Advanced Statistical Modelling
Least-squares, generalized least-squares and likelihood estimation. Theory and application of parametric and non-parametric regression models such as splines, penalized splines, and generalized additive models. Assessment and treatment of data issues including missingness and measurement error. Credit will be granted for only one of DATA 410, STAT 310, STAT 410, or STAT 538. [3-2-0]
STAT 547 (2-15) d Topics in Statistics
Topics chosen from different areas within the field of statistics, such as time series, longitudinal and multi-level modelling, multivariate analysis, machine learning, resampling and permutation methods, smoothing and filtering, survival analysis, sports analytics and spatial statistics. Content will be determined so as to complement course offerings and meet the needs of the students. With the permission of the department head, this course may be taken more than once on a different topic. [3-0-0]
STAT 560 (3) Probability and Stochastic Processes
Theory of probability, including random variables, expectation, conditional expectation, generating functions, modes of convergence of random variables and their distributions. Applications to random models such as Markov, Poisson, birth-death, Gaussian and diffusion processes. [3-0-0]
