 # Econometrics and Data Analysis

Course TypeCourse CodeNo. Of Credits
Discipline CoreSLS2EC2114

Semester and Year Offered: 2nd Semester (Winter Semester 2019)

Course Coordinator and Team: Krishna Ram

Email of course coordinator: krishna@aud.ac.in

Prerequisites:

Knowledge of mathematics (especially Algebra and Calculus), statistics, and Basic Econometrics at level of, say, Gujarati’s Essentials of Econometrics is required.

Course Objective:

It is a tool course, which is designed to equip students for analysing real life data, related to economics in particular and social science in general, with the help of mathematical knowledge and computer software. In today’s world students are required to objectively analyse the problem at hand and this is true in social sciences as well. This course will acquaint the students with theoretical knowledge as well as implementation of theory through software applications like STATA. The main thrust of the course will be on cross-section data analysis, along with an introductory component on univariate time series analysis.

Course Outcome:

On successful completion of this course students will be able to:

1. Use matrix approach of OLS estimation, hypothesis testing and diagnostic testing.
2. Estimate multivariate linear regression model using cross-sectional data set.
3. Identify all possible misspecification in the CLRM using econometric software package, STATA.
4. Use the instrument variable technique for the model estimation.
5. Estimate ARIMA model using econometric software package, Eviews.
