Interactive Dummy Variable Mechanics
Interactive Dummy Variable Mechanics is a free, interactive learning demo from the Econometric Theory and Empirical Analysis with Stata course on Lykke. It helps you build intuition for Dummy Variable Trap, Linear Probability Model (LPM), Instrumental Variables (IV), Difference-in-Differences (DiD). Play with it directly in your browser — it features interactive elements you can explore. Observe how intercept and slope shifts affect the estimated coefficients. This demo lives in the “Qualitative Data and Advanced Causal Inference” section of the course.
How to use this demo

- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Dummy Variable Trap
- Linear Probability Model (LPM)
- Instrumental Variables (IV)
- Difference-in-Differences (DiD)
Frequently asked questions
What does the Interactive Dummy Variable Mechanics demo do?
Interactive Dummy Variable Mechanics Regression Blueprint Drag the circular handles to manipulate the model. Interactive Dummy Variable Mechanics lets you explore this hands-on instead of only reading about it.
What Econometric Theory and Empirical Analysis with Stata concept does Interactive Dummy Variable Mechanics teach?
Introduces dummy variables for categorical data and advanced methods for identifying causal effects in the presence of endogeneity. It focuses on Dummy Variable Trap, Linear Probability Model (LPM), Instrumental Variables (IV), Difference-in-Differences (DiD) from the “Qualitative Data and Advanced Causal Inference” section.
How does Interactive Dummy Variable Mechanics fit into the Econometric Theory and Empirical Analysis with Stata course?
This course provides a comprehensive introduction to econometrics, focusing on the application of statistical methods to economic data to estimate causal relationships and test theories. Students learn the theoretical f… This demo is the interactive piece for the “Qualitative Data and Advanced Causal Inference” section.

What will I understand better after using Interactive Dummy Variable Mechanics?
You'll build intuition for Dummy Variable Trap, Linear Probability Model (LPM), Instrumental Variables (IV), Difference-in-Differences (DiD) — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Econometric Theory and Empirical Analysis with Stata alone.
