Metodologia e applicazioni della statistica (STREAM) 
STatistics REsearch: Applications and Methods

Il laboratorio si occupa dello sviluppo di metodi statistici e della loro applicazione in una varietà di discipline.
La ricerca metodologica si concentra sull’inferenza bayesiana e frequentista, in ambito parametrico e non-parametrico. Specifici contributi metodologici riguardano i dati categoriali, le carte di controllo, la meta analisi, i valori estremi, le serie temporali, i dati spaziali, l'analisi di sensibilità.
Il gruppo si occupa anche di statistica computazionale e dello sviluppo di software statistico in particolare con il linguaggio R.
È particolarmente attivo nell'applicazione dei metodi statistici in collaborazioni multidisciplinari con ricercatori e professori dell’Università Ca’ Foscari e di altri istituti di ricerca. Le applicazioni recenti riguardano, per esempio, la climatologia, l'economia, le scienze ambientali, l'epidemiologia, l'idrologia, la medicina, la sociologia e lo sport.
