  • Teaching Applied Statistics (91893)

    Primo anno di Economics and Entrepreneurship (LM-56), Curriculum unico
    Credits (CFU): 9,00
  • Teaching Applied Statistics (91950)

    Primo anno di Global economy and business (LM-56), Dual Degree with Samara State University of Economics
    Credits (CFU): 12,00

    Program:
    The aim of this course is to provide students with some logical and technical statistical tools which may be exploited to tackle economics and business issues starting from data. The exploratory data analysis and model building perspective is adopted. Room is devoted to applications and case studies.

    Course contents: Basics of statistical inference. Simple Linear Regression. Multiple Regression. Weighted regression. Polynomial Regression. Regression with categorical predictors. Dummy variables. Transformations. Regression Diagnostics: Residuals, Outliers and Influence. Nonconstant Variance. Variance Stabilizing Transformations. Graphs for Model Assessment. Variable Selection. Nonlinear Regression. Binary response regression. Experimental and observational studies/variables.

    Instructional Format
    The class will meet for 2 hours (gross of interclass break), four times a week, for a total of 42 sessions. After an introduction aimed at providing the needed background, participants are required to read the materials related to the class and to be prepared prior to coming to class.
    Classes will consist of a lecture by the instructor, to be followed by a discussion of the main topics and the assigned case. Main points about the materials and all doubts brought up by the students will be addressed by the instructor during the class.
    Time for presentations of homework solutions by students is also allowed within the total amount of class hours (presentations will be approximately scheduled once a week).

    workload expectations
    All students are expected to spend in the average at least 2,5 hours of time on academic studies outside of, and in addition to, each hour of class time. That is, the average student will spend around 18 hours of work at home each week of the term (maybe you are not the average student, though!).

    Reference books:
    Listed below are the required course textbook and additional readings. These are required materials for the course and you are expected to have constant access to them from the very beginning of the course for reading, highlighting and note-taking. It is required that you have unrestricted access to each. Access to additional sources required for certain class sessions may be provided in paper or electronic format consistently with applicable copyright legislation.
