Introductory Econometrics

*Introductory Econometrics* is designed for undergraduate students of Bodoland University in alignment with the National Education Policy (NEP) 2020, which emphasizes multidisciplinary learning, analytical skills, and research orientation. The book provides a clear and systematic introduction to econometric methods, enabling students to connect economic theory with empirical data. The text begins with the basic concepts of econometrics, including the nature of data and the role of statistical inference in economic analysis. It then develops the classical linear regression model using Ordinary Least Squares (OLS), with a strong focus on interpretation of coefficients, hypothesis testing, and model validation. These foundational tools help students build essential quantitative and analytical competencies. Key econometric problems such as multicollinearity, heteroscedasticity, autocorrelation, and specification errors are discussed in a simplified yet rigorous manner, along with their practical implications. The book also introduces time series concepts such as stationarity, unit roots, and basic dynamic models, reflecting the growing importance of data-driven economic analysis. This aligns with NEP 2020?s emphasis on local context and application-based learning. Each chapter includes learning objectives, solved examples, and practice questions to facilitate both classroom teaching and self-study.
