STAT340: Introduction to Data Modeling II, Fall 2022

This course teaches students to apply statistical methods to learn from data. Topics include one- and two-sample inference; an introduction to Bayesian inference and associated probability theory; linear and logistic regression models; the bootstrap; and cross-validation. Students use an integrated statistical computing environment to explore and analyze data, develop models, make inferences, and communicate results in a reproducible manner through a project-oriented approach to learning.
