Logit regression is one of the fundamental tools in econometrics for modeling binary outcome variables. This article is primarily helpful for students learning STATA to interpret the results of a logit regression, especially in the context of assignments as well as coursework. We will use a practical example as well as provide coding illustrations for making the process clear and engaging. 

Introduction to Logit Regression

Logit regression, also known as logistic regression, is in use when your dependent variable is binary (e.g., yes/no, 1/0). Thus, instead of predicting a continuous outcome, it also models the probability of a certain outcome that is occurring. This is done by transforming the results from a linear regression into probabilities using the logistic function.

Understanding the Basics

Logits and Odds Ratios: This indicates that the basic form of logit regression does not actually predict probabilities.  Instead, it models the log-odds of an event happening.  The log-odds are then exponentiated to find the odds ratio to get more interpretations.  The odds ratio can be understood to provide a measure of how much the odds of your outcome either increase or decrease with a one-unit change of your predictor variable.

Coefficients: From STATA software, the change arising from a unit increase in your predictor as described in the logit regression output is presented as Coef.  When the coefficient sign is positive, it means odds of the outcome are higher.  When the coefficient sign is negative, it means odds of the outcome are lower. 

At the end of this guide, you should be able to comprehend various elements of logit regression analysis, especially applied when interpreting results obtained from analyzing econometrics data typically given in your course work assignments.  Ok, let’s do an example now and do the coding side a bit and keep it as simple as we want.

How to Perform a Logit Regression in STATA

Let us walk through how to perform a logit regression in STATA using a practical example. We will examine the relationship between education level and support for gay marriage using the dataset GSS2016.DTA.

First, make sure your dependent variable is binary. In our case, the dependent variable is support for gay marriage. If this variable isn’t binary, you’ll need to recode it.

recode marhomo (1/2=1 "Favor")(3/5=0 "Neutral or oppose"), gen(marhomo_r) label variable marhomo_r "Favorable view toward gay marriage"

To estimate a logit regression, use the following command:

logit marhomo_r educ, nolog

Also, Read our blog on Linear Regression in STATA for one-of-a-kind assignment help.

Menu Method:

Click on "Statistics" > "Binary outcomes" > "Logistic regression".

Fill in the dependent and independent variables.

Click on the "Reporting" tab to choose "Report estimated coefficients".

Click "OK".

Interpreting the Output

Here is a sample output:

Coefficients of the model. For educ, the coefficient is 0.153, indicating the log-odds of supporting gay marriage increase by 0.153 for each extra year of education.

Converting to Odds Ratios

Log-odds are not intuitive. Convert coefficients to odds ratios using the or option:

logit marhomo_r educ, nolog or

Odds Ratio: For educ, the odds ratio is 1.165, meaning each extra year of education increases the odds of supporting gay marriage by nearly 16.5%.

To control for additional variables like age and gender, extend the model:

logit marhomo_r educ age female, nolog or

Interpreting the output:

educ: Still significant with an odds ratio of 1.165. 

age: Odds ratio of 0.977, indicating older individuals are less likely to support gay marriage. 

female: Not significant in this model.
