Course Readings, Files and Examples

Class Calendar

In this course students will:
(1) Learn to identify key statistical issues in observational studies and methods and study designs to address issues of confounding.
(2) Become proficient with advanced statistical methods for observational studies: methods for missing data, matching based inference, sensitivity analysis, propensity score methods, instrumental variables, directed acyclic graphs, and marginal structural models. You should know which methods are useful in different situations, and which conditions have to be checked for the method to be applicable.
(3) Be able to perform detailed data analyses on a variety data using the statistical computation environment R. You should be able to implement all the methods presented in this course.
Prerequisites: HRP261 and 262, or Stat 209 (HRP 239) or by permission of instructor

Textbooks
Required
Design of Observational Studies, Paul Rosenbaum, 1st Edition (Springer) Available online:   Stanford access

Computation
We will make extensive use of the statistical computation and programming environment R. It is free and open source, and it has become the de facto standard for statistical analyses in most areas of academia and industry. Current version of R for spring quarter will be R version 3.2.4 to be released on 2016-03-10. For references and software: The R Project for Statistical Computing   Closest download mirror is Berkeley  The CRAN Task Views provide an organization and overview of the many R packages.
One specialized resource this course will draw from is Paul Rosenbaum's software page
Many students may also use or be interested in an editor for R (beyond emacs or command line). Professor Baiocchi will be using RStudio, download at .

Course Components, Student Work
Homeworks: Suggested problems will be posted each week. Solutions will be posted at approximately the same time. These problems are for your own use and will not be collected or graded.
Problem Sets. During the Spring Quarter there will be two, take-home problem sets. TH1 covers weeks 1 - 5; TH2 covers weeks 6 - 9; see class calendar. These problem sets will be the basis for grading the two-unit enrollment. No collaboration or external assistance is permitted.   
Problem Set 1
  
Problem Set 2

Third unit enrollment, Project/Presentation. If you are enrolled for three units credit, the additional unit requirement to complete a small project and give a short presentation (approximately 15 minutes with handout). These presentations will be scheduled in the last two weeks of the quarter.


Note to auditors. With our new room assignment we now have space for auditors.
The Registrar does have a form (no-fee) for faculty, staff, post-docs: Application for Auditor or Permit to Attend (PTA) Status
