Mission & Content Summary
MISSION
CONTENT SUMMARY
Students without any background in basic statistics (elements of descriptive statistics, estimation, confidence intervals, tests, basic elements of the linear regression model) are advised to attend the preparatory statistics course.
Part I – Statistical tools for data analysis:
- Linear regression. Assumptions, estimates and their interpretation. Models with categorical covariates. Tests on the coefficients of the model. Interactions and transformations. Multicollinearity issues. Predictions. Residual analysis. Introduction to regression models for panel data.
- Logistic regression. Interpretation of the coefficient estimates. Tests on the coefficients of the model. Evaluation of the quality of a model. Predictions. Multinomial logistic regression.
- Time serie analysis. Time series decomposition (trend, seasonality, error), autocorrelation function, stochastic models (ARMA, ARIMA), predictions.
Part II – Mathematical tools for data analysis:
- Valuation of investments.
- Valuation of financial transactions.
- Valuation of options (binomial model).
Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
- Understand mathematical and statistical analyses of economic and business phenomena.
- Know the theoretical and operational tools required for the understanding and the implementation of such analyses.
APPLYING KNOWLEDGE AND UNDERSTANDING
- Deeply analyze and interpret economic and business phenomena, identifying and applying properly, even through the use of appropriate scientific software, suitable mathematical and statistical methodologies.
Teaching methods
- Lectures
- Practical Exercises
DETAILS
Exercise sessions devoted to the analysis of economic and business data are proposed; to this aim the softwares presented during the course are used. Students are invited to take an active part in the analysis.

ATTENDING AND NOT ATTENDING STUDENTS
The assessment for the course includes 3 in-class tests that are carried out during the exercise sessions in the first part of the course (statistics) and a final written exam.
The in-class tests consist of short tests, with closed-ended questions, aimed at checking students' understanding and their ability to apply (with the R/RStudio software) the concepts and techniques presented during the lectures. Each of the 3 tests has a maximum score of 2.
The final written exam covers the material presented in both parts of the course: statistics and mathematics. It consists of open-ended questions and exercises designed to test the students' ability to apply the knowledge acquired. Some questions require the use of the software presented during the course.
Each of the two parts of the written examination (the one relating to statistical tools and the one relating to mathematical tools) has a maximum mark of 31.
The final grade V for the examination is calculated as follows:
V=max{(2/3)·[I+(25/31)·S]+(1/3)·M , (2/3)·S+(1/3)·M},
where:
I=total score of the two in-class tests (maximum 6)
S=score of the statistics part of the final written exam (maximum 31)
M=score of the mathematics part of the final written exam (maximum 31)
The score is rounded up to the nearest integer number (upwards if the decimal point is 0.5).
If the in-class tests are not taken, the score I is equal to 0.
The closed-answer questions mainly aim to test the knowledge of the mathematical and statistical tools for the analysis of economic and business data.
The open-answer questions mainly aim to test the ability to apply the acquired knowledge.
