I am pleased to announce that Ceteris Lab has now been updated through Module 8, expanding the platform’s interactive econometrics curriculum from foundational concepts to more advanced regression analysis.
The newly available Module 8: Heteroskedasticity introduces one of the most important practical issues in applied econometrics. Students learn how changing error variance affects regression inference and how to respond using robust standard errors, diagnostic tests, weighted least squares, and feasible GLS.
Module 8 includes:
- Clear theoretical explanations
- Mathematical formulas and step-by-step interpretation
- Visual demonstrations of changing variance
- Residual and diagnostic graphs
- Breusch-Pagan and White tests
- Heteroskedasticity-robust standard errors
- Robust t tests and joint hypothesis tests
- Weighted least squares
- Feasible GLS
- Prediction under heteroskedasticity
- Linear probability models with robust inference
- Interactive activities, quizzes, datasets, and live Python practice
With Modules 1 through 8 now available, Ceteris Lab covers:
- Foundations of econometrics
- Simple regression
- Multiple regression
- Statistical inference
- OLS asymptotics
- Functional forms, interactions, and prediction
- Qualitative information and binary variables
- Heteroskedasticity and robust estimation
Ceteris Lab is designed for students, educators, researchers, and professionals who want to learn econometrics through theory, mathematics, visualization, real and simulated data, quizzes, AI-assisted learning, and hands-on Python analysis.
