This course, the first of two, focuses on the development and use of single-equation econometric models that enable analysts to better understand their economic/business landscape and to improve their ability to make sound economic/business forecasts. Through hands-on exercises, participants gain knowledge of the practical elements of applied econometric analysis. The overall aims are to sharpen the quantitative, statistical, and analytical skills of participants in dealing with problems and issues related to business and economics as well as to improve communication skills in reporting findings to decision makers.

To learn more intermediate/advanced topics, consider registering for the Advanced Topics in Applied Econometrics course.

Skills Gained

  • Develop and use single-equation econometric models.
  • Improve your ability to make sound forecasts.
  • Sharpen your quantitative, statistical, and analytical skills.

  • Use SAS software to conduct econometric analyses.

Who Can Benefit

  • Academicians, economists, forecasters, and government and business analysts

Prerequisites

  • Before attending this course, you should:
  • Have a basic knowledge of SAS software, including SAS procedures such as PROC UNIVARIATE and PROC REG.

Data Considerations and Ordinary Least Squares Estimation of Single-Equation Econometric Models

  • Data.
  • Getting a feel for the data.
  • Massaging the data.
  • Estimation of the Simple Linear Regression model.
  • SAS output of the simple linear regression of total personal bankruptcy (TPB) on real gross domestic product (RGDP).
