3/27, today we discussed the nonlinear OLS regression in Xs in terms of polynomial, logarithmic, and interaction terms. You can download slides with all details in the lecture from the schedule now.
3/26, tomorrow we will extend OLS regression to nonlinear regression. You can download slides with blanks in the lecture from the schedule, which is updated.
3/20, today we have learned that how to use Hypothesis Testing and Confidence Intervals in OLS regression. You can download slides with all details in the lecture from the schedule now which is updated.
3/19 Tomorrow, I will review the basic idea of Hypothesis Testing in your statistics courses at first, then extend it in OLS regression.You can download slides without details from the schedule.
3/13 Today, I extended the simple OLS regression to multiple OLS regression.Hope you have a good understanding of the content. If you have any questions, please feel free to ask me.You can download slides with details from the schedule. Next week, I will introduce the hypothesis testing and confidence intervals in regression. If possible, you’d better review the content of hypothesis testing and confidence intervals in statistics courses.
3/6 Today,I will introduce the first method and the most important method in this course: regression.You can download slides without details from the schedule.
Tomorrow will be the first lecture of the course. I have prepared a few slides for it. You can download them from the schedule. Looking forward to meeting you all tomorrow.
Welcome to the course website for the 2025 edition of Introduction to Econometrics, also known as “Intro’Metrics”(计量经济学). This course is delivered by Prof. Zhaopeng Qu and his teaching assistants at the Business School, Nanjing University.
Course Description
This course introduces students to modern econometrics, mainly focusing on causal inference techniques, and their applications in economics and other social sciences. The course focuses more on intuition and practical examples, while keeping the mathematical content to a minimum. Notably, matrix notation is not used.
The goal is to help students develop a solid theoretical background in introductory level econometrics, an ability to implement modern econometric methods, and a critical thinking about empirical studies in economics and other social sciences.
Specifically, we will learn several common econometric research design techniques that aim to credibly estimate causal effects on economic and social relationships:
Randomized Controlled Trial(RCT)
Regression(OLS)
Matching(Matching)
Instrumental Variables(IV)
Regression Discontinuity Designs(RDD)
Panel Data and Differences-in-Differences(DID)
At the end, students will use at least one of them above to finish a team-based empirical research proposal.
