Course Content:

Chapter 1: Least Squares Regression with One Explanatory Variable

Master the fundamentals of least squares regression. This chapter introduces the least squares method for fitting a straight line to data, focusing on the underlying algebra. No prior probability or statistics knowledge is required. Learn to derive the OLS (Ordinary Least Squares) formula and understand key concepts such as trendlines, residuals, fitted values, and R-squared. We'll explore how to perform these analyses using both Excel and EViews.

Chapter 2: Introduction to Probability Theory

Build a strong foundation in probability theory and statistics. Understand random variables, distribution functions, expected value, variance, and covariance. Learn about conditional moments, a crucial concept in econometrics for understanding error terms and their impact on model assumptions.

Chapter 3: Linear Regression with One Explanatory Variable

Formalize the core linear regression model. This chapter focuses on the single-explanatory variable case, introducing the key assumption of exogeneity. Reinterpret the OLS formula as an estimator of unknown parameters. Explore the Gauss-Markov assumptions and their implications for the variance of the OLS estimator. Finally, learn about hypothesis testing and confidence intervals within the linear regression framework.

Chapter 4: Linear Regression with Multiple Explanatory Variables

Expand your understanding to multiple linear regression. Learn how to extend the OLS formula to accommodate several explanatory variables. While we won't delve into matrix algebra, we'll emphasize how these formulas are implemented in software like Excel, EViews, Stata, and more. Explore adjustments to inference procedures and introduce new statistical tests. Address the challenge of multicollinearity and investigate nonlinear regression models and dummy variables. Conclude with an analysis of heteroscedasticity and techniques for addressing it.

Chapter 5: Time Series Data Analysis

Dive into the world of time series data. Address the unique challenges of working with time-dependent data, including the issue of nonstationary data and the potential for spurious results. Focus on stationary time series and explore dynamic models like ADL (Autoregressive Distributed Lag) and AR (Autoregressive) models. Learn about autocorrelation and methods for testing for and estimating models in its presence.

Chapter 6: Endogeneity and Instrumental Variables

Address the critical issue of endogeneity – when explanatory variables are not truly exogenous. Explore the consequences of using endogenous variables in econometric analysis, including model misspecification, errors in variables, and the simultaneity problem. Learn about instrumental variables and how to use them to consistently estimate parameters in models with endogenous variables. Understand both the instrumental variable estimator and the generalized instrumental variable estimator.

Chapter 7: Binary Choice Models

An introduction to microeconometric models, starting with the binary choice model. Learn how to use similar methods to those in Chapter 4, resulting in the linear probability model. Address the limitations of the linear probability model (probabilities outside the 0-1 range) and explore alternative models like probit and logit. Introduce the maximum likelihood estimation technique for these models.

Chapter 8: Non-Stationary Time Series Models

A deeper look at non-stationary time series data. Investigate the consequences of using non-stationary data and learn methods for determining whether your time series is stationary.

Chapter 9: Panel Data Analysis

An introductory overview of panel data – data collected over both cross-section and time. Focus on the error component model, exploring the **
