## STATISTICAL COMPUTING

### STATA

## Program

### Updated A.Y. 2018-2019

The aim of this course is to acquaint students with the basics of Stata (and its use for applied economics), and the basics of Pyhton (to work on webscraping tasks). The course will be mostly focused on micro-econometrics. Topics to be covered in the first semester (Gagliarducci) include: dataset management, descriptive statistics, graphics, loops, linear regression, instrumental variable models (IV), panel data models, event-study analysis, regression discontinuity (RD). Topics to be covered in the second semester (Rovigatti) include: scraping standard websites, extracting usable information and storing it in machine-readable format.

**Course prerequisites and material**

Students are supposed to be attending, or have attended, the course of Statistics and Econometrics, and having some knowledge of the concepts of lists and websites. Knowledge of html and programming best practices could be a plus, while being able to manage comma separated files is a prerequisite. In each class, we will compile a code on the scheduled topic (see below).

**Final exam**

PASS or FAIL. The final exam consists of a take-home assignment to be returned (via email) at least one week before the expected exam registration.
