What is Econometrics?
Definition and Purpose
Econometrics is a branch of economics that applies statistical and mathematical methods to analyze economic data. Its primary purpose is to give empirical content to economic theories, test hypotheses, and forecast future economic trends. By integrating economic models with real-world data, econometrics enables economists to quantify relationships between variables and make informed decisions.
Key Components of Econometrics
- Data Collection and Management
- Model Specification
- Estimation Techniques
- Hypothesis Testing
- Forecasting and Policy Analysis
