University of Bologna
Aims, objectives and learning outcomes
The course provides an introduction to the use of statistical and econometric methods in the social sciences, with particular but not exclusive reference to applications in economics. Among the themes treated, of particular relevance are the problems of estimation and test of hypotheses within the multivariate linear regression model, instrumental variable estimation, discrete choice models, and the analysis of panel data.
The course is applied in nature, and use will be made of the software
, during a series of ten "Stata labs". Students also will have to write a "Stata project" which will account for half of the final grade.
Students taking this class should have taken an introductory course in statistics, and in particular they should be familiar with the following concepts: random variables, main distribution of probabilities, estimation of the mean of a population and test of hypothesis. Students who do not satisfy these prerequisites may take the course anyway, but they should be prepared to work hard to remedy their ignorance.
At the end of the course, successful students will be able to autonomously employ the methods considered in the course, while appropriately interpreting the results of their analyses.
The exercises using Stata will take place on Thursdays between 3pm and 5pm at the
Labic Computer Lab
. There the students will also find a number of personal computers, with Stata installed, for autonomous use during the lab's opening hours.
The main textbook is: Stock, James and Mark W. Watson. 2012. Introduction to Econometrics. 3rd edition. Pearson (indicated in what follows as [SW])
Also relevant is: Ray C. Fair. 2012. Predicting Presidential Elections and Other Things. 2nd. edition. Stanford University Press (The PDF file of the first edition is:
). A copy is available at the Central library.
To review the topics whose knowledge is a prerequisite for this course, students may peruse any introductory text in statistics. Students who can read Italian may want to consider: Pacini, B. and Picci, L. 2001. Introduzione alla Statistica, Clueb (indicated in what follows as [PP]). A limited number of copies of this textbook may be borrowed from the library.
