The Gabors Data Analysis ecosystem
We wanted to create more than a textbook: an ecosystem of open materials for learning and teaching data analysis. Everything below is free and lives in our GitHub organization — code, courses, interactive apps, and an open-access book.
Core textbook materials
da_case_studies
Full code for all 47 case studies in R, Python, and Stata — reproduce every figure and table in the book. Our most popular repository.
Data on OSF
Raw and clean versions of all datasets used in the case studies, hosted on the Open Science Framework.
Learn to code, from zero
Full open coding courses that accompany the textbook, taking you from zero to doing the case studies yourself. More about the courses →
Coding in R
Coding course to complete Data Analysis in R — by Ágoston Reguly with Gábor Békés.
Coding in Python
Python course to accompany the Data Analysis material — by Ádám Víg and Péter Duronelly with Ágoston Reguly and Gábor Békés.
Coding in Stata
Stata course for the textbook material — by László Tőkés with Ágoston Reguly and Gábor Békés.
Data analysis with AI
Data Analysis with AI — the course
A full open course on doing data analysis with LLMs and agentic tools: eight sessions, assignments, case studies, and a capstone.
Data Analysis with AI — the open book
An open-source Quarto book for social science students, companion to the course. Free to read online (CC BY-NC-SA 4.0).
Interactive apps and simulations
Small tools we built for teaching — play with the concepts instead of just reading about them.
Gabors Interactive Data Analysis
A Shiny app to explore the hotels-europe case study data interactively (beta).
Difference-in-differences simulator
Interactive panel data and event study simulation — see how DiD estimates behave under different setups (chapters 22–24).
Frisch–Waugh–Lovell explorer
A Shiny dashboard illustrating the FWL theorem, with a growth-regression example (Mankiw–Romer–Weil) and simulated data (chapter 10).
Austrian hotels wrangling dataset
A realistic, synthetically generated multi-table hotel dataset for practicing data wrangling and joins.
R vs Python vs Stata — debate data
Poll and survey data from the December 2022 CEU language-debate event. Anonymous; share if you use it.
