Learning outcomes
Al termine del corso, lo studente conosce i modelli statistici che sono alla base dell'attività di estrazione di conoscenza da grandi quantità di dati (Big Data). In particolare, lo studente è in grado di: - strutturare un processo di data mining; - scegliere, tra gli strumenti metodologici, quelli più adeguati a raggiungere l'obiettivo in esame; - interpretare criticamente i risultati.
Course contents
- Introduction to data and Rstudio
- Statistical Learning
- Resampling methods: cross-validation
- Linear models: OLS estimator, Gauss-Markov hypotheses and inference, interpretation, model selection. Nested/Non-nested models. Polinomial functions. Violation of the hypotheses: residual analysis and specification tests (heteroschedasticity, non-normality), robust OLS.
- Model selection and Regularization: stepwise selection, ridge and lasso regression.
- Classification: logistic regression
- Time series: definition, residual analysis and specification tests (structural break and autocorrelation), robust OLS, time series components, forecasting with classical methods, statistical performance of forecasting methods.
