Advanced Approaches to the
Analysis of Observational Data
BIOSTAT 215 Spring 2017 (3 units)


A common goal of observational clinical or epidemiologic research is to estimate the causal effect of particular exposures or interventions on some health outcome. While causation-oriented research has long been practiced, recent methodologic work has more sharply placed into view what it means and what is needed to estimate causal effects. In particular, it is now recognized that conventional stratification or regression approaches to reduce confounding in observational research may, in certain settings, fail to estimate unbiased causal effects. This course will describe more advanced methods that may succeed in estimating causal effects in cases where standard approaches break down.

At the end of the course, students will understand:

  • Potential outcomes, average causal effects, and local average causal effects;
  • Marginal and conditional causal effects;
  • Conditions where standard regression methods fail to estimate causal effects;
  • How and when to use propensity scores;
  • What to do when the time-dependent confounders of an intervention also mediate its effects;
  • New-user analyses;
  • How and when to use instrumental variables;
  • How to use treatment assignment as an instrument to estimate treatment efficacy; and
  • Mediation analysis.

Epidemiologic Methods (EPI 203), Biostatistical Methods II (BIOSTAT 208), and Biostatistical Methods III (BIOSTAT 209). Exceptions to these prerequisites may be made with the consent of the Course Director, space permitting.

Regression Methods in Biostatistics by Vittinghoff et al. Springer, 2012.

Stata Statistical Software (Stata Corporation, College Station, TX) will be used; version 13 or higher is acceptable. A six-month student license for Stata/IC is the least expensive option that will be suitable to complete all course assignments, but Stata/SE is recommended for robust future use. The TICR Program has arranged for a sizeable discount for UCSF-affiliated personnel.

Books may be purchased either through the publisher or a variety of commercial venues (e.g., Amazon.com).


Grades will be based on weekly homeowrk assignments and a take home final examination.

Students not in full-year TICR Programs who satisfactorily pass all course requirements will, upon request, receive a Certificate of Course Completion.
