## Advanced Topics in Applied Econometrics
This sequel to Introduction to Applied Econometrics focuses on intermediate and advanced topics in working with econometric models. This course enables analysts to better understand their economic/business landscape and to improve their ability to make sound forecasts. Through applications, 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.
