The course will provide a practical introduction to modern high-dimensional function fitting methods — a.k.a. machine learning (ML) methods — for efficient estimation and inference on the treatment effects and structural parameters in empirical economic models. Every participant will use R to immediately internalize and use the techniques in their own academic and industry work. All lectures, except the introductory one, will be accompanied by the R-code that can be used to reproduce the empirical examples in the lectures during the lectures. Thus, there will be no gap between theory and practice.
Editions: This is the 6th edition of the course to be given in CEMMAP UK and Warwick UK. Previous editions were given at NBER 2014, MIT in 2015 and 2016 as parts of the 14.387 course “Applied Econometrics”, Sciences Po Paris in 2015, and in the Summer School of Econometrics of the Bank of Italy in Perugia 2015.
Causal Inference in Approximately Sparse Linear Structural Equations Models.
Understanding of the Inference Strategy via the Double Partialling Out and Adaptivity.
ML Methods for Prediction = Reduced Form Estimation. Evaluation of ML Methods using Test Samples.
ML Methods for Causal Parameters -- “Double” Machine Learning for Causal Parameters in Treatment Effect Models and Nonlinear Econometric Models
Scalability: Working with Large Data. MapReduce, Hadoop and all that
Please bring your computer to class. Install R and R-studio. Install packages “hdm”, “glmnet”, “nnet”, “randomForest”, “rpart”, “rpart.plot”, “gbm” from cran (e.g. type install.packages(“gbm”)) If you are not familiar with R, try out several introductory tutorials that are available online. Please read and understand the idea of cross-validation (k-fold cross-validation) to prevent overfitting, and bias and variance tradeoffs in nonparametric estimation. I will be mentioning these briefly in class, but I will count on you understanding this background concepts. A good reference is “Elements of Statistical Learning” which is available from Tibshirani’s website.
