Assumptions of the Classical Linear Regression Model (CLRM) – With Clear Examples

Online Econometrics Resources /

The Classical Linear Regression Model (CLRM) is the foundation of econometrics. It ensures that Ordinary Least Squares (OLS) estimators are BLUE — Best Linear Unbiased Estimators. For this to hold true, certain assumptions must be satisfied. Let’s explore them step by step. 1. Linearity in Parameters 2. Zero Mean of Error Term 3. No Correlation […]

Machine Learning and Panel Data: Revolutionizing Econometric Analysis

Online Econometrics Resources /

IntroductionIn the evolving landscape of econometrics, panel data—a dataset that tracks multiple entities over time—has long been a gold standard for understanding dynamic economic behaviors. From evaluating policy impacts to forecasting market trends, its ability to capture both cross-sectional and temporal variations makes it indispensable. However, the rise of machine learning (ML) is reshaping how

Synthetic Control Method-ML-Econometrics

Synthetic Control Methods (SCM) with Machine Learning (ML) and Traditional Econometrics

Online Econometrics Resources /

Synthetic Control Methods (SCM) with Machine Learning (ML) and traditional econometrics share the goal of causal inference, but they differ fundamentally in their approach, assumptions, tools, and applications. Here’s a breakdown of their key differences: 1. Core Philosophy & Methodology Traditional Econometrics SCM + ML Focuses on parametric models (e.g., linear regression, IV, DID) with strict assumptions (linearity, exogeneity). Uses non-parametric or

Quantile Regression for Economists: How to Analyze Data Beyond the Mean with Tailored Insights

Online Econometrics Resources /

Quantile Regression for Economists: How to Analyze Data Beyond the Mean with Tailored Insights Quantile regression, introduced by Koenker and Bassett in 1978, is a technique that extends the traditional linear regression framework to estimate the conditional quantiles of the response variable rather than the conditional mean. In other words, instead of focusing solely on

Structural Vector Autoregressions (SVARs): An In-Depth Look at Identifying Structural Shocks and Understanding Their Macroeconomic Effects

Online Econometrics Resources /

Structural Vector Autoregressions In the realm of macroeconomic analysis, Structural Vector Autoregressions (SVARs) have emerged as a vital tool for identifying and understanding the impact of structural shocks on economic systems. Unlike standard Vector Autoregressions (VARs), SVARs incorporate theoretical constraints to discern structural shocks and their effects, making them essential for evaluating policy impacts and
