101 Introductory Statistics
This course will give an introduction to descriptive and inferential statistics. Topics
include descriptive statistics; graphical display of data, random variables and
probability distributions, parameter estimations, hypothesis testing and simple
linear regression. Students will learn to use statistical software tools; to identify
bias in data collection; to organize and summarize data; to make inferences from
data and to be able to test the significance of the results. Acceptable for credit
in the Faculties of Arts and Business, and the Departments of Human Kinetics,
Human Nutrition and B.Sc. Nursing. STAT 101.H will focus on applications to health
sciences and STAT 101.B will focus on applications to business and economics.
Credit will be granted for only one of STAT 101, STAT 201, STAT 224, STAT 231,
PSYC 290(292), HKIN 301. Three credits.
224 Probability and Statistics for Engineers
This course covers probability laws and the interpretation of numerical data,
probability distributions and probability densities, functions of random variables,
joint distributions, characteristic functions, inferences concerning mean and
variance, tests of hypotheses, linear regression, and time series analysis.
Engineering applications are emphasized and statistical computer packages are
used extensively. Credit will be granted for only one of STAT 224, STAT 101(201),

445 Statistical Learning and Data Mining
The course covers the most current techniques used in data mining and machine
learning and their background theoretical results. Two basic groups of methods
are covered in this course: supervised learning (classification or regression) and
unsupervised learning (clustering). The supervised learning methods include
Recursive Partitioning Tree, Random Forest, Linear Discriminant and Quadratic
Discriminant Analysis, Neural Network, Support Vector Machine. The unsupervised
learning methods include Hierarchical Clustering, K-means, K-nearest-neighbour,
model-based clustering methods. Furthermore, the course also covers the
dimensional reduction techniques such as LASSO and Ridge Regression, and
model checking criteria. Prerequisites: CSCI 161, STAT 224 or 231 or permission
of instructor. Three credits. Offered 2017-2018 and in alternate years.

This course will cover a selection of current statistical topics, such as sampling
theory, time-series analysis, stochastic processes, design and analysis of
experiments, bootstrap methods, multivariate analysis, and bioinfomatics. Three
credits. See http://sites.stfx.ca/mscs/stats_courses for more information.
491 Senior Seminar
Cross-listed as CSCI 491 and MATH 491. The purpose of this non-credit course
is to assist students in carrying out senior paper research, composition, and
oral presentation. Students will present their research topic in the fall term and
