@alecasa.bsky.social and Davide Ferrari (@unibz.bsky.social) tackle the problem of selecting the number of components in Gaussian mixture models, where traditional single-model criteria like BIC often overlook model selection uncertainty.

Dati, economia e sfide reali. La prima edizione del Data4Econ Hackathon Il 3 giugno si terrà la prima edizione dell’unibz Data4Econ Hackathon, una competizione dove si incontrano analisi statistica, data science ed economia.

I partecipanti, suddivisi in team, lavoreranno su dataset reali forniti da #Alperia e #GruppoDolomitiEnergia (sponsor dell’evento), sviluppando modelli predittivi e interpretazioni economiche innovative. @alecasa.bsky.social
