STAT 230b / STAT 530b/ PLSC 530b Introductory Data Analysis

Survey of statistical methods: plots, transformations, regression, analysis of variance, clustering, principal components, contingency tables, and time series analysis. The R computing language and Web data sources are used.

Term: Spring
Day/Time: Tuesday & Thursday, 9:00-10:15

STAT 238a / STAT 538a Probability and Statistics

Fundamental principles and techniques of probabilistic thinking, statistical modeling, and data analysis. Essentials of probability, including conditional probability, random variables, distributions, law of large numbers, central limit theorem, and Markov chains. Statistical inference with emphasis on the Bayesian approach: parameter estimation, likelihood, prior and posterior distributions, Bayesian inference using Markov chain Monte Carlo. Introduction to regression and linear models. Computers are used for calculations, simulations, and analysis of data.

After MATH 118 or 120. 

Term: Fall
Day/Time: Tuesday, Thursday 1:00pm - 2:15pm

STAT 325a / STAT 625a Case Studies

Statistical analysis of a variety of statistical problems using real data. Emphasis on methods of choosing data, acquiring data, assessing data quality, and the issues posed by extremely large data sets. Extensive computations using R. Limited enrollment, by permission only.

Term: Fall
Day/Time: Tuesday, Thursday 9:00am - 10:15am (tentative) + 1 HTBA

STAT 365b / STAT 665b Data Mining and Machine Learning

Techniques for data mining and machine learning are covered from both a statistical and a computational perspective, including support vector machines, bagging, boosting, neural networks, and other nonlinear and nonparametric regression methods. The course will give the basic ideas and intuition behind these methods, a more formal understanding of how and why they work, and opportunities to experiment with machine learning algorithms and apply them to data. After STAT 242b.

Term: Spring
Day/Time: Monday & Wednesday, 11:35am - 12:50pm
