Title: Applications of Causal Inference Methods
Description: Application of potential outcomes formulation for causal inference to research settings including: mediation,
compliance adjustments, time-1 time-2 designs, encouragement designs, heterogeneous treatment effects, aggregated data,
instrumental variables, analysis of covariance regression adjustments, and implementations of matching methods.

Course Overview
Note: This course was structured before the new world order of March 2020 as one two-hour class meeting per week.
The way things worked out this quarter, reality dictates Thursday for complete posting for the week's lecture and materials.
Brief Course Outline Unit 1. Extensions of RCT
Analyzing Encouragement Designs
Assessing Mediation in experimental studies
Identifying Moderation in experimental studies (heterogeneous treatment effects)
The wisdom of Compliance Adjustments (for binary and measured compliance);
Analysis of Regression Discontinuity Designs (systematic assignment based on a covariate)
Unit 2. Legacy Methods for Causal Inference from Observational Data (good and bad)
Regression adjustments (analysis of covariance) in observational studies
Instrumental Variables methods for observational studies
Failures of traditional Path Analysis (and Structural Equation Models)
Interpreting associations: Spurious Correlation and Simpson's Paradox
Multilevel data and Contextual Effects
Reciprocal Causal Effects and non-recursive models
Unit 3. Historical and Modern Methods for Matching in Observational Data
Case-Control, case-referent matching sudies
Subclassification matching
Propensity Score matching examples
Unit 4. Time-1, Time-2 data in experimental and observational studies.
Experimental Designs Cross-over designs
Experimental Designs Comparing groups on time-1, time-2 measurements: repeated measures anova vs lmer OR the t-test
Observational studies Economist's differences in differences (or diffs in diffs with matching) for observational studies.
Observational studies Lord's paradox; pre-post group comparisons.
Observational studies Exogenous Variables and Correlates of Change (use of lagged dependent variables)
Additional Special topics Interrupted Time-series designs; Current implementations of value-added analysis

Grading, Exams, and Credit Units
Stat209B/EPI239/Ed260A is listed as Letter or Credit/No Credit grading for 2-units
For Winter 2021 grading for the 2-units will be based on a 'take home'(i.e. do at home) Problem Set.
Also as you will see, for each week's content a number of Review Questions with Solutions are posted.
Statistical computing
Class presentation will be in, and students are encouraged to use, R (occasionally, some references to SAS and Mathematica).
Current version of R is R version 4.0.3 released 2020-10-10
For references and software: The R Project for Statistical Computing Closest download mirrors in the past, UCLA and Berkeley, seem no longer avaliable, pick your fave anywhere in the world.
The CRAN Task Views provide useful overviews/navigation for the almost infinite set of R-packages. Task Views that cover contents of this course include CRAN Task View: Statistics for the Social Sciences; CRAN Task View: Econometrics and CRAN Task View: Psychometric Models and Methods .
Relevent Texts (optional).
Causal Inference in Statistics, Social and Biomedical Sciences: An Introduction, Guido Imbens and Don Rubin, 1st Edition (Cambridge University Press) Stanford access
Design of Observational Studies, Paul Rosenbaum, 1st Edition (Springer). Available online: Stanford access
