Variable selection is one of the hardest issues in multivariate regression models. Several methods have been proposed to select smaller subsets of informative variables. In this work, a new variable selection method is proposed in the context of multiple function-on-function linear regression (MFFLR) model. By merging functional data analysis with group Lasso method, a principal components’ regression approach has been adopted to estimate the MFFLR model.
The proposed technique allows to reduce a large number of discrete observations highly correlated for each curve to a functional form that conserves all relevant information and obtain a more sensible and interpretable model for the environmental problem at hand.
The method has been tested with real data obtained from the automatic reporting platform run by Regional Agency for the Environmental Protection of Abruzzo Region (Italy) with the aim of investigating the relationship of PM10 with other interesting meteorological variables.
Keywords: variable selection; group Lasso; functional data analysis; environmental data.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city.
