Multiple Regression in Stata

This tutorial shows how to fit a multiple regression model (that is, a linear regression with more than one independent variable) using Stata. The details of the underlying calculations can be found in our multiple regression tutorial. The data used in this post come from the More Tweets, More Votes: Social Media as a Quantitative Indicator of Political Behavior study from DiGrazia J, McKelvey K, Bollen J, Rojas F (2013), which investigated the relationship between social media mentions of candidates in the 2010 and 2012 US House elections with actual vote results.

Regression with Nominal Independent Variables

In our previous tutorials, we discussed simple regression and multiple regression with continuous variables, but what happens when our independent variable is nominal rather than interval? The data used in this tutorial are again from the More Tweets, More Votes: Social Media as a Quantitative Indicator of Political Behavior study from DiGrazia J, McKelvey K, Bollen J, Rojas F (2013), which investigated the relationship between social media mentions of candidates in the 2010 and 2012 US House elections with actual vote results.

Multiple Regression

Multiple Regression A prior tutorial described simple regression as a mapping of a single predictor to an outcome variable. This tutorial covers the case when there is more than one independent variable, also known as multiple regression. Although simple regression is a useful tool for extracting information about bivariate relationships that goes beyond what we get from a correlation or t-test, the real power of regression comes from its ability to incorporate multiple independent variables.
