## Regression Analysis & Causality using Stata

• Location: Cass Business School, Bunhill Row, London EC1Y 8TZ
• Duration: 2 days (19th October 2017 - 20th October 2017)
• Software: Stata
• Level: Introductory
• Delivered By: João Cerejeira ; Miguel Portela
• Topic: Data visualization, Econometrics, Microeconomics, Regression analysis

### Course Overview

The course is designed for academic staff, including master/PhD students, who have a basic knowledge of statistics/econometrics and/or Stata; and those who deal with different types of data and projects in their day-to-day work. The course will also be of interest to non-academic participants who regularly apply data analysis from an econometric perspective.

This course will focus on a number of applications available within Stata, including:

• Organising and handling data
• Data analysis
• Linear regression: OLS and GLS
• Causal inference with Stata: differences-in-differences and instrumental variables
• Producing analysis output: graphs and tables

### Day 1 - Overview & Linear Regression

Session 1: - Stata Refresh

• From command line to ‘do files’
• Import, reshape and combine data
• Statistics & Graphics: an introduction
Session 2: Linear Regression & Stata (I)
• Computing linear regression estimates
• Presenting and discussing regression estimates
• Sampling distribution of regression estimates
• Hypothesis tests
• Specification issues: graphically analysing regression data
Session 3: Linear Regression & Stata (II)
• Interaction terms and marginal effects.
• Heteroskedasticity: causes and test;
• The robust estimator of the VCE;
• The GLS and FGLS estimator.
Session 4: Exercise & output export
