A copula-based multivariate hidden Markov model for modelling momentum in football
Ötting, Marius; Langrock, Roland; Maruotti, Antonello (Journal article; Peer reviewed, 2021)We investigate the potential occurrence of change points—commonly referred to as “momentum shifts”—in the dynamics of football matches. For that purpose, we model minute-by-minute in-game statistics of Bundesliga matches ... -

Estimating the size of undetected cases of the COVID-19 outbreak in Europe: An upper bound estimator
Rocchetti, Irene; Böhning, Dankmar; Holling, Heinz; Maruotti, Antonello (Journal article; Peer reviewed, 2020)Background While the number of detected COVID-19 infections are widely available, an understanding of the extent of undetected cases is urgently needed for an effective tackling of the pandemic. The aim of this work is ... -
Estimating the undetected infections in the Covid-19 outbreak by harnessing capture-recapture methods
Böhning, Dankmar; Rocchetti, Irene; Maruotti, Antonello; Holling, Heinz (Journal article; Peer reviewed, 2020)Objectives A major open question, affecting the decisions of policy makers, is the estimation of the true number of Covid-19 infections. Most of them are undetected, because of a large number of asymptomatic cases. We ... -
Hidden semi-Markov-switching quantile regression for time series
Maruotti, Antonello; Petrella, Lea; Sposito, Luca (Journal article; Peer reviewed, 2021)A hidden semi-Markov-switching quantile regression model is introduced as an extension of the hidden Markov-switching one. The proposed model allows for arbitrary sojourn-time distributions in the states of the Markov-switching ... -
Insights from cardiopulmonary exercise testing in pediatric patients with hypertrophic cardiomyopathy
Gallo, Giovanna; Mastromarino, Vittoria; Limongelli, Giuseppe; Calcagni, Giulio; Maruotti, Antonello; Ragni, Luca; Valente, Fabio; Musumeci, Beatrice; Adorisio, Rachele; Rubino, Marta; Autore, Camillo; Magrì, Damiano (Journal article; Peer reviewed, 2021)The usefulness of cardiopulmonary exercise test (CPET) in adult hypertrophic cardiomyopathy (HCM) patients is well-known, whereas its role in pediatric HCM patients has not yet been explored. The present study investigates ... -
Modelling clusters of corporate defaults: Regime-switching models significantly reduce the contagion source
Berentsen, Geir Drage; Bulla, Jan; Maruotti, Antonello; Støve, Bård (Journal article; Peer reviewed, 2022)In this paper, we report robust evidence that the process of corporate defaults is time-dependent and can be modelled by extending an autoregressive count time series model class via the introduction of regime-switching. ... -
Nowcasting COVID-19 incidence indicators during the Italian first outbreak
Alaimo Di Loro, Pierfrancesco; Divino, Fabio; Farcomeni, Alessio; Jona Lasinio, Giovanna; Lovison, Gianfranco; Maruotti, Antonello; Mingione, Marco (Journal article; Peer reviewed, 2021)A novel parametric regression model is proposed to fit incidence data typically collected during epidemics. The proposal is motivated by real-time monitoring and short-term forecasting of the main epidemiological indicators ... -
Old and new equations for maximal heart rate prediction in patients with heart failure and reduced ejection fraction on beta-blockers treatment: results from the MECKI score data set
Magrì, Damiano; Piepoli, Massimo; Gallo, Giovanna; Corrà, Ugo; Metra, Marco; Paolillo, Stefania; Filardi, Pasquale Perrone; Maruotti, Antonello; Salvioni, Elisabetta; Mapelli, Massimo; Vignati, Carlo; Senni, Michele; Limongelli, Giuseppe; Lagioia, Rocco; Scrutinio, Domenico; Emdin, Michele; Passino, Claudio; Parati, Gianfranco; Sinagra, Gianfranco; Correale, Michele; Badagliacca, Roberto; Sciomer, Susanna; Di Lenarda, Andrea; Agostoni, Piergiuseppe (Journal article; Peer reviewed, 2022)Aims Predicting maximal heart rate (MHR) in heart failure with reduced ejection fraction (HFrEF) still remains a major concern. In such a context, the Keteyian equation is the only one derived in a HFrEF cohort on optimized ... -
