Engineering students interested in a survey of the mathematical theory of probability and statistics should consider the pair STAT UN3203: Probability theory and UN3204: Statistical inference. Students seeking a quicker overview that focuses more on probability theory should consider STAT GU4001. STAT GU4109 (6 pts) covers the same material as UN3203 and UN3204 in a single semester. STAT UN3205: Linear regression models takes UN3203 and UN3204 as prerequisites; like other advanced offerings in statistics, it covers both theory and practical aspects of modeling and data analysis.
STAT GR5203, GR5204, and GR5205 are the equivalent of UN3203, UN3204, and UN3205, respectively; but graduate students may not register for UN3203, UN3204, or UN3205.
Advanced offerings in probability theory, stochastic processes, and mathematical finance generally take STAT UN3203 as a prerequisite; advanced offerings in statistical theory and methods generally take STAT GR5204 and, in several cases, UN3205 as prerequisites; an exception is STAT GU4220: Data mining, which has a course in computer programming as prerequisite and STAT UN3204 as corequisite. STAT GR5291 is an advanced survey of applied statistical methods.
Please note that STAT UN3000 has been renumbered as UN3203 and STAT UN3659 has been renumbered as UN3204. For a description of the following course offered jointly by the Departments of Statistics and Industrial Engineering and Operations Research, see Industrial Engineering and Operations Research.
