Course topic:

Learn how to model social and economic networks and their impact on human behavior. How do networks form, why do they exhibit certain patterns, and how does their structure impact diffusion, learning, and other behaviors? We will bring together models and techniques from economics, sociology, math, physics, statistics and computer science to answer these questions. The course begins with some empirical background on social and economic networks, and an overview of concepts used to describe and measure networks. Next, we will cover a set of models of how networks form, including random network models as well as strategic formation models, and some hybrids. We will then discuss a series of models of how networks impact behavior, including contagion, diffusion, learning, and peer influences. You can find a more detailed syllabus here: http://web.stanford.edu/~jacksonm/Networks-Online-Syllabus.pdf You can find a short introductory videao here: http://web.stanford.edu/~jacksonm/Intro_Networks.mp4

This course starts every four weeks. The next session begins October 10.

The course is aimed at people interested in researching social and economic networks, but should be accessible to advanced undergraduates and other people who have some prerequisites in mathematics and statistics. For example, it will be assumed that students are comfortable with basic concepts from linear algebra (e.g., matrix multiplication), probability theory (e.g., probability distributions, expected values, Bayes' rule), and statistics (e.g., hypothesis testing). Beyond those concepts, the course is self-contained.

The active course run for Statistical Learning has ended, but the course is now available in a self paced mode. You are welcome to join the course and work through the material and exercises at your own pace. When you have completed the exercises with a score of 50% or higher, you can generate your Statement of Accomplishment from within the course.

The course will remain available for an extended period of time. We anticipate the content will be available until at least August 2, 2017. You will be notified by email of any changes to content availability beforehand.

This is an introductory-level course in supervised learning, with a focus on regression and classification methods. The syllabus includes: linear and polynomial regression, logistic regression and linear discriminant analysis; cross-validation and the bootstrap, model selection and regularization methods (ridge and lasso); nonlinear models, splines and generalized additive models; tree-based methods, random forests and boosting; support-vector machines. Some unsupervised learning methods are discussed: principal components and clustering (k-means and hierarchical).

This is not a math-heavy class, so we try and describe the methods without heavy reliance on formulas and complex mathematics. We focus on what we consider to be the important elements of modern data analysis. Computing is done in R. There are lectures devoted to R, giving tutorials from the ground up, and progressing with more detailed sessions that implement the techniques in each chapter.

The lectures cover all the material in An Introduction to Statistical Learning, with Applications in R by James, Witten, Hastie and Tibshirani (Springer, 2013). The pdf for this book is available for free on the book website.

First courses in statistics, linear algebra, and computing.

Trevor Hastie is the John A Overdeck Professor of Statistics at Stanford University. Hastie is known for his research in applied statistics, particularly in the fields of data mining, bioinformatics and machine learning. He has published four books and over 180 research articles in these areas. Prior to joining Stanford University in 1994, Hastie worked at AT&T Bell Laboratories for 9 years, where he helped develop the statistical modeling environment popular in the R computing system. He received his B.S. in statistics from Rhodes University in 1976, his M.S. from the University of Cape Town in 1979, and his Ph.D from Stanford in 1984. Professor Hastie is an elected fellow of the Institute of Mathematical Statistics, the American Statistical Association, the International Statistics Institute, the South African Statistical Association and the Royal Statistical Society. He has received a number of awards and honors, including the Myrto Lefkopolous award from Harvard in 1994, the Parzen Prize for Innovation in 2014, and the Distnguished Rhodes University Alumni award in 2015.

Robert Tibshirani is a Professor in the Departments Health Research and Policy and Statistics at Stanford University. In his work he has made important contributions to the analysis of complex datasets, most recently in genomics and proteomics. His most well-known contribution is the Lasso, which uses L1 penalization in regression and related problems. He has co-authored over 200 papers and three books. Professor Tibshirani co-authored the first study that linked cell phone usage with car accidents, a widely cited article that has played a role in the introduction of legislation that restricts the use of phones while driving. He is one of the most widely cited authors in the entire mathematical sciences field. Professor Tibshirani is a Fellow of the American Statistical Association, the Institute of Mathematical Statistics and the Royal Society of Canada. He won the prestigious COPSS Presidents's award in 1996, the NSERC Steacie award in 1997 and was elected to the National Academy of Sciences in 2012.

Will Fithian and Sam Gross produced and formatted the quiz questions and review questions. Daniela Witten helped present some of the material in Chapter 5. Wes Choy managed the video production. Greg Maximov filmed and edited most of the course videos, as well as the interviews and group recordings. Greg Bruhns, Monica Diaz and Marc Sanders assisted with Open edX.

No, a free online version of An Introduction to Statistical Learning, with Applications in R by James, Witten, Hastie and Tibshirani (Springer, 2013) is available from that website. Springer has agreed to this, so no need to worry about copyright. Of course you may not distribiute printed versions of this pdf file.

Yes. You get R for free from http://cran.us.r-project.org/. Typically it installs with a click. You get RStudio from http://www.rstudio.com/, also for free, and a similarly easy install.

More and more people are starting to tap into the barely touched opportunities of data. Supporting marketing campaigns with more market data, understanding and preventing product failures with real-time measures, retaining customers with detailed behavior monitoring, or fighting fraud with real-time analysis of hundreds of millions of transactions are among the many examples that demonstrate how pervasive data has become across all lines of business. After years of buzz and mixed results, data technology, management techniques, and processes have gained maturity. Data is now more readily accessible to everyone. In this online course, students will learn how to engage with data and discover concrete and actionable business intelligence techniques to gain immediate control of data and deliver accurate insights, manage change to drive project acceptance, and design lean and sustainable processes. The course will also include detailed case studies and feature expert guest speakers to provide invaluable and fascinating field experience.

Course topic:

This course is self-paced and is provided free of charge. There are no due dates, and students are welcome to work through as much or as little of the material as they wish. There is no instructor involved, and no credit, Statement of Accomplishment, or any type of verification or certification of completion is given. The course is simply here for people who want to learn more about Statistics.

The Statistical Reasoning course contains four main units that have several sections within each unit.

**Exploratory Data Analysis:** This unit is organized into two sections – Examining Distributions and Examining Relationships. The general approach is to provide students with a framework that will help them choose the appropriate descriptive methods in various data analysis situations.

**Producing Data:** This unit is organized into two sections – Sampling and Designing Studies

**Probability:** This course contains a streamlined version of probability that forgoes the classical treatment of probability in favor of an empirical approach using relative frequency. This course includes only those concepts that are necessary to support a conceptual understanding of the role of probability in inference. For the full, classical treatment of Probability, students may see the OLI Probability and Statistics course.

**Inference:** This unit introduces students to the logic as well as the technical side of the main forms of inference: point estimation, interval estimation and hypothesis testing. The unit covers inferential methods for the population mean and population proportion, inferential methods for comparing the means of two groups and of more than two groups (ANOVA), the Chi-Square test for independence and linear regression. The unit reinforces the framework that the students were introduced to in the Exploratory Data Analysis for choosing the appropriate, in this case, inferential method in various data analysis scenarios.

Throughout the course there are many interactive elements. These include: simulations, “walk-throughs” that integrate voice and graphics to explain an example of a procedure or a difficult concept, and, most prominently, interactive activities in which students practice problem solving, with hints and immediate and targeted feedback.

The course is built around a series of carefully devised learning objectives that are independently assessed.

**Note about Probability and Statistics vs. Statistical Reasoning: **One of the main differences between the courses is the path through probability. **Probability and Statistics** includes the classical treatment of probability. **Statistical Reasoning** places less emphasis on probability than does the Probability and Statistics course and takes an empirical approach.

Knowledge of basic algebra.
