Course outline, objectives and learning outcomes

Recent years have seen a massive increase in the availability of large data sets. In this course we will cover some of the techniques that have been developed to analyze such data sets. Particular attention will be given to precise estimation, variable selection, and hypothesis testing. We will also see how to implement the some of the techniques in R.

Topics covered

1. The Lasso and some of its asymptotic properties when the dimension of the model is fixed. 

2. Introduction to the oracle property. The adaptive Lasso as an example of an estimator possessing the oracle property. 

3. The adaptive Lasso for instrumental variable selection. 

4. The adaptive elastic net for generalized method of moments. 

5. Upper bounds on the estimation error in the `∞-norm and variable selection via thresholding. 

6. Finite sample oracle inequalities for the Lasso when the number of variables is larger than the sample size.

7. Oracle inequalities and inference in high-dimensional VAR models.  Some results from applications to large macroeconomic data sets.

8. Uniformly valid inference in high-dimensional models when the number of variables is larger than the number of parameters.

9. How to use the glmnet and the lars package in R to implement Lasso-type estimators.
