Certificate Course on Computer Applications in Economic Analysis
Prerequisites: This is an applied econometrics course using the popular statistical software packages used by empirical economists/ analysts. What distinguishes these modules is the adoption of the modern learning-by-doing approach to teaching econometrics, which emphasizes the application of econometrics to real world problems. The focus is on understanding the theoretical aspects that are critical in applied work and the ability to correctly interpret empirical results.
Course Structure: The content of the course will be presented by means of practical hand-on sessions. The sessions will demonstrate the concepts and methods of statistics with practical examples of different dimensions. The course will cover wide data sets Solution of some of the problem set will be discussed in the classes.
Course Objectives: This course is for graduate students.
There will be a strong emphasis on the concepts and application of probability theory, random variables, distributions, sampling theory, statistical inference, correlation and regression.
Statistical inference techniques such as estimation and significance testing are important in the fitting and interpretation of econometric models.
Correlation and regression analysis are essential tools for measuring relationships between variables and for prediction.
This course should be of value to those intending to study any course involving economic modeling and econometrics.
Outcome: By the end of the module you should be competent in applying the mathematical and statistical tools used in econometrics and should be able to:
- Handle real data with confidence
- Apply econometric methods of analysis to new circumstances
- Understand the conditions under which particular estimators are appropriate
- Apply the theoretical methods to numerical data
- Write and present technical material lucidly
- Understand the basic theory of the ordinary least squares, generalized least squares and panel data models
- Apply appropriate estimators to the type of numerical data given in seminar exercises and computing classes
- Interpret empirical results in applied economics literature
At final stage, students will be asked for assessment tests which include submission of the assignments and formal examination.
Grade & Examination
Grades for the course will be computed based on the following allocation:
- Final exam (80%) [short objective types + practical exercises + result interpretation and report writing on the basis of given dataset]
- Assignments (three) (20%)
Texts: As stand-alone resources will be provided, there will be no need to rely on particular texts. However, there are several good texts are now available which can be used as supplementary materials, including:
