Title: Understanding Violations of Classical Linear Regression Models (CLRMs) - Part 1: Assumptions & Heteroscedasticity

Description:
Welcome to our deep dive into the violations of Classical Linear Regression Models (CLRMs)! In this first part of our series, we explore the fundamental assumptions of CLRMs and focus on one major violation: heteroscedasticity.

🔍 What You'll Learn:

Assumptions of CLRMs: Discover the key assumptions that underpin CLRMs, crucial for accurate and reliable regression analysis.
Heteroscedasticity Defined: Understand what heteroscedasticity is and how it can affect your regression models.
Causes of Heteroscedasticity: Learn about the common causes that lead to heteroscedasticity in data.
Consequences of Heteroscedasticity: Find out the implications of heteroscedasticity on the precision and validity of your regression results.
Remedial Measures: Explore effective strategies to detect, address, and correct heteroscedasticity, ensuring robust regression analysis.
Stay tuned for future episodes where we'll delve into autocorrelation and other critical violations of CLRMs.
